Depends on the balance of the home, furniture, cabinet style, trim, etc., etc. It is all only a part of the puzzle. It typically needs to jive somewhat with the exterior styling as well.

I tend to be a little more casual traditional. I’m thinking of a simple design flat cabinet front with a bit of an inside edge. I will probably do the kitchen island with a raised panel to mix things up. My furniture is mostly traditional as our my lamps and accessories. The exterior is pretty traditional as well.

Do you mean a flat 2 panel door with traditional sticking?

Yes.
