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.
Best of luck,
