also forgot to mention:

the peninsula would have a stack stone veneer, granite countertop and step up wood bar

I have stacked stone on my fireplace and I think it gives a somewhat rustic vibe. For that reason, I would suggest a more traditional door style over a slab door which can be more contemporary. I think white vs stained cabinetry is a very personal decision. If you know you want to get white cabs in your forever home, why not try the maple in your for now home. I am not sure what stain wood work with the concrete floors.

Slab doors are veneered for grain match, and while they are durable enough for home use, I wouldn't trust them to stand up to careless renters. Ditto with paint. I love painted cabinets and plan to buy them for my kitchen, but paint can chip, stain cannot, and is therefore more durable in the long run.

To sum up, my recommendation would be for stained maple with a traditional Shaker door style in a home that might be rented out. It should not be difficult to pick the door stain to compliment your floor stain - if you want help just post some images. To lighten things up choose a white granite and bs tile, and a light colored paint.
