In this case, since you have both finishes, you can choose any of them. On the one hand, you should choose a vaporized beech front like the rest of the carpentry, but the furniture finish is also important since you "saw" the room. Beech and white are two shades that coordinate very well, so you don't have too much trouble. How about choosing doors with large translucent glass panels and white or beech molding? In this way you introduce another neutral finish that lightens the result and combines well with any of the other materials.
