Take a sample home and put lemon juice on it. What you will find is that the etches on dark marble show up white. Not at all attractive. And that's why only the white marbles are truly popular for kitchen counters. They show etches much less than the dark ones. Possibly use it as a vertical accent somewhere in your home (NOT a shower), but I wouldn't use it on any horizontal surface. Maybe a gorgeous full height backsplash where you have no uppers on a wall....or in an entry way directly facing you as a focal point. Think of it as art, not a work surface.

Take photos of your cabinets and space with you when you shop for granite. Another Idea is to visit Home Depot or Lowes and buy some Single 12x12 granite tiles as samples just to get an idea of what might work. They have lots of choices. Not exactly what you want but close enough to help you zero in. The tiles can then be returned.

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?

Hi Purvi, for open plan kitchen you can change the fridge door position to front facing instead of balcony facing. One more option is, you can plan for pocket doors. The advantage of that is if you wish to have the open feeling you can keep it open or close it. My personal advise will be, instead of asking for individual queries you should consult a person and take complete details as per your requirements.
