I recently did an Austrailian Cyprus floor. Looked neat. But that may be too cabin like for you. If you have dark cabinets i would go light floor. Nice contrast and also dark floors show dust almost immediately after cleaning. Also light floors tend to make rooms look larger. Just my opinion.

My cabinets are dark. I wanted a light granite. I chose Bianco Romano. I have paired it with floor tile that might be similar in tone to yours as they are matte white with a grayish cast. Sorry I don't have any pictures to show you yet. The floor is in, but the cabs will not be installed till next week, but I think the combination is going to be awesome! Other light granites I explored were Kashmir White, Bianco Antico & Aaran White. These all would give a high contrast look. There are quite a number of mid tone granites if you want to blend rather than contrast. If you are wanting a dark granite, you can always keep your paint & backsplash light to balance out with your floor.

I'd look for a tinted white/ barely there gray, as I prefer a white/neutral kitchen. as in this entry space gray door and light walls. You need to know the tones of gray cabinet paint- cool or warm.. Take a cabinet door to BM or Sherwin Williams or other paint store.....Ask staff to match it to one of their colors. Research palettes with that color. SW has several books that have pre-coordinated palettes --nearly all have a few gray shades.... Or web search example below. My current project: Laundry/ utility room was decided on colors we liked SWSea Salt and Eider White. The cabinet color is SWMindful Gray after reviewing many paint swatches. Then, last night I came across this, which reinforced the selections ETA. I hated the BM and SW color visualizers, those programs were not helpful. Search kitchens with gray cabinets. If a page doesn't have wall paint details, then save the image and use a Reverse Image search, which will show you to other sites with that image, like Instagram. It takes a bit of effort, but it is well worth it . Try: https://www.reverseimagesearch.com 

Ooh, I like the Skipping Stone color! Thanks, everyone, for your great ideas! I was thinking a white or eggshell leather sofa/sectional -- my dining table is dark with warm white denim slipcovered chairs -- would that be weird?
