This is also the only room in the house that will have an ac we are renters and that is nonnegotiable at the moment and the house in general and especially that room gets quite hot in the summer.
As far as I can tell, based on square footage alone I would be looking for a btu unit, but I am wondering if might be better given the location of the room and those additional factors.

My question relates to how the kitchen bump up intersects with the common advice that if you oversize your unit, then it can lead to short cycles that leave you with humidity and wear out the equipment. There are different ways to cut this where I could calculate anything from 7, to 15, units, but am considering to go with a 12, unit on balance.
Does this seem reasonable? All your presumption about oversizing a unit, short cycles, wearing out, higher bills are on point. Hope this helps a bit.
