Have you been to visit some kitchen showrooms? You can customise the photo search here on Houzz quite a bit. For example, you can simply select [dark wood[(https://www.houzz.com.au/photos/kitchen-design-ideas-with-dark-wood-cabinets-phbr1-bp~t_10444~a_17-103) cabinet finish in the filter options. Then add more filters like floor colour, kitchen layout, cabinet style, wall colour etc if you wish. Leave the benchtop and splashback options open and see what results you get. You can then save any photos that appeal to your ideabook.

White-matte cabinets (flat panel, not shaker) and white bench (or maybe epoxy sealed marine ply??...siriuskey can tell you about that), mirror splash. Love the ceilings. I personally would go for a modern, stream-line, no handles, integrated appliances look. This space has real potential to be very cool, even with the slate. It doesn't need any more more texture or darkness. This is a nice kitchen, you should be able to sell it on ebay.

I would vote for the top example here. Itr gives an earthy tone to the room and yet is still bright and wont show every piece of dust or food.

I would not use a white stone, such as a Carrera Marble in any kitchen, no matter what the colour of the cabinetwork due to the porosity and risk of staining. Better to use a reconstituted stone benchtop which is manufactured to look like stone, such as Caeserstone, or one of its competitors. If you have the budget look at Dekton for whitish stone-like benchtops. As far as the monochomatic scheme it can look very smart, but will depend on the amount of natural light and artificial light in the room. Perhaps consider doing the overheads in white, and paying special attention to your choice of splashback. You may also want to consider how long you will live in your home, as black kitchens are very much on trend, and in ten years time they will have dated and look very 2018.
