A few preliminary points:
- 'New York' was of course 'New Amsterdam' for the larger part of the mid 17th century (until 1664). This is important, as the status and nature of slavery (and of free blacks) changed in the years following the British takeover.
- From the 1640s, Dutch West India Company had a system of 'half-freedom' which could eventually lead to full freedom.
- 'Paternalistic' seems a more appropriate word than 'kindly' when talking about slave owners. The kindest thing a slave owner could do would be to free his/her slaves, in which case (of course) he/she would no longer be a slave owner.
- For context, in 1664, New Amsterdam had a population of around 1,500, of whom 300 were slaves. About one in eight citizens were slave owners.
Domestic Servants
Female domestic slaves were common during the Dutch colonial period:
Slave women, usually no more than one per household, aided white women
(free and indentured) with cooking, cleaning, and child care.
Source: Leslie M. Harris, 'In the Shadow of Slavery: African Americans in New York City, 1626-1863' (University of Chicago Press, 2003)
Male slaves performed many kinds of tasks, including skilled ones, but it seems that most were used for physically demanding tasks. This does not preclude, of course, male slaves working as domestics. They almost certainly did. (see also this article)
Whipping
This did happen, but there is too little information available to say how common it was. Administering punishment was considered a very low status occupation so
In New Amsterdam, a slave named Pieter administered punishments
including whipping, maiming, and execution.
Source: Harris
There was a case of a public whipping of a child for theft in 1661:
Her punishment was so harsh that one scholar has noted, “she seems
to have been the only child the court ordered beaten in this way”
The scholar in question would appear to be Susanah Shaw Romney in “Intimate Networks and Children’s Survival in New Netherland in the Seventeenth Century,” Early American Studies: An Interdisciplinary Journal 7, no. 2 (Fall 2009)
As the colony had few laws regarding slaves, there may not have been a law concerning the (private) administration of punishments such as whipping by slave owners.
Slaves earning money for their labour
On your third point, slaves could receive wages but the evidence I've found relates to the Dutch West India Company (WIC) rather than to individual owners:
WIC remitted wages to at least five slaves who, in 1635, petitioned
the metropolitan authorities in Holland to order the WIC to pay them
for their labor

Children of slave and slave owner playing together
On your fourth point, given that
the northern urban slaves of colonial New York City generally lived in
their masters’ houses and in this respect led more confined, closely
monitored lives than their counterparts in the rural South,
it is not unlikely that black and white kids did play together. Also, racism was much less evident during the Dutch period:
Blacks and whites had coequal standing in the colonial courts, and
free blacks were allowed to own property (Jews, however, were not).
They intermarried freely with whites and in some cases owned white
indentured servants.
Schools were also integrated:
As early as 1636, Dutch officials in New Amsterdam had educated black
and white children in integrated schools.
Unfortunately, the source doesn't say if these black children were those of free parents, but it is evident that race was not a barrier to these children mingling.
Also, the Dutch Reform Church (which was strongly opposed to slavery) married and baptized Africans until 1655. Although not evidence of slave owner and slave kids playing together, this does (with other evidence in this post) indicate that the colonist at the time held a wide range of views; this makes generalizing difficult.
Freeing of Slaves
On your last point, freeing of slaves was (by the 2nd half of the 17th century at least) uncommon but not unheard of:
Few New York City slaveowners rewarded their slaves with the gift of
freedom. In a rare act of voluntary manumission, the widow Christiana
Cappoens stipulated in her will that after her death Isabell, her
female slave, should be freed from bondage and receive manumission
papers documenting her free status. Cappoens also left Isabell several
items of modest value: one small gold hoop ring, one iron pot, one
kettle, a bed, and pillows.
Christina Cappoens died in 1693, admittedly a little late for your time frame. Earlier, in 1626, the Dutch West India Company (WIC) granted 'half freedom' to 11 male slaves and their wives:
A written agreement stated that the black petitioners were “free and
at liberty on the same footing as other free people here in New
Netherland.” But according to the “half-freedom” bargain, the WIC
manumitted the 11 enslaved male petitioners and their wives on the
condition that they were obligated to labor for the WIC when called on
to serve and that their offspring were the WIC’s property.
Later, the DWIC granted the same status to more than 20 other slaves, but these measures were in effect forced upon the company by the Indian wars and the desperate shortage of soldiers (many slaves had previously served in the military).
Also,
On September 4, 1664, on the eve of the English conquest, Petrus
Stuyvesant granted the petition of eight men “praying to be manumitted
and made entirely free.”
Petrus Stuyvesant was Director General of the New Netherland Colony (which included New Amsterdam, the capital). Some slaves of individual owners also gained their freedom:
Besides some WIC slaves, a few slaves of individual slaveowners
managed to attain freedom. For example, in 1649, Manuel de Spanje
purchased his freedom from Phillip Jansz Ringo for 300 guilders, to be
paid over three years, and in 1654, Captain Pieter Jacobsz and Jan de
Graue manumitted Bastiaen d’Angola...freed as a reward for
faithful service....
However,
slaves found it more difficult to obtain freedom from individual
owners than from the company
Finally, it is worth noting that
Slaves, white and black indentured servants, and free black and white
workers in the seventeenth century held more rights and experiences in
common in New Amsterdam, and indeed in North America, than would be
true in the eighteenth and nineteenth centuries.

is this depiction of slavery accurate and commonplace enough for the time and culture - or is this fanciful writing?
Aren't you setting up a false dichotomy? Such a slaveowner could certainly conceivably have existed, without it being "commonplace". – Semaphore♦ Feb 26 '19 at 6:56
