I can take a stab at guessing here. The lowers are just plain old shaker style, probably in an oak (though ash can have this grain pattern-but few cabinet makers offer ash). I cannot tell what the rail cut is, (rift or quartersawn oak) but the insets are an oak veneer panel. If it is oak, the finish is a water-based poly with probably a tiny bit of white, meant it keep it from yellowing. (Oil finish would make it look more yellow.) It could also be some very light tonal stain like sunbleached. But my guess, is like the floors, these are oak, in a natural finish like BONA Natural. Any competent cabinet maker can do these.

How tall are the top cabinets together?
