Really like the counter top combination. To create a finished look (rather than a haphazardly thrown together look), you should probably use the same color on both vertical spaces -- the same color as is between the diamond shapes on the wall.

Option 4. I would not have more than 2 different cabinet finishes. Darker, grounded look for the base and island, with lighter, airier look for the uppers would balance the room.

Your choices don't flow well to me. The flooring in your photo is pretty (very dark...are you okay with it showing every footprint, smudge, and dust bunny? If so, that's fine). From all of your options there I would do white cabinets with the Himalaya White granite. But you said ignore the granite. :) I would go for the gray cabinets with white quartz everywhere in that case, but personally I'd worry about gray cabinets being very dated in a few years. Is there another quartz option that you could pair with the white cabinets that is light in color and maybe has some movement, like LG Bianco Drift?

I have pretty much the same colour combination except that the upper cabinets are in silver... also i went for black granite countertop as white is difficult to maintain in our Indian cooking conditions with usage of oil, turmeric and spices....if your budget permits and you can maintain white marble it does give a very sophisticated look...
