Making it with one of these woods will be REALLY nice and you're right to leave it simple. I first tried to make myself a real carbon fiber board out of CF fabric and epoxy, but it was really a mess to polish and I had to abandon. I just kept a very small carbon fiber panel for the switches.
Plywood and black suede was chosen because my car is white and I wanted a black interior. It's obviously much easier.
With a "nobel" wood panel the cutting will have to adjust perfectly so take good car to confirm every dimension from your own car and give a little margin for adjustments. The varnishing/polishing will be easier than with CF/epoxy so you shouldn't have much trouble here.
Good luck end enjoy!
