Our new home has oak trim with matching 6 panel doors throughout...trying to find good examples of how white trim (because I really want to pain all the trim white!) works with oak doors (without having to replace the nice new doors!). I think this works...?
simple 2 panel interior door. with a modern styled home I think either a 2 panel door or a flush door looks best, though in a pinch there are some great 5 - 6 panel doors that could work as well. but for me it's always best to keep it simple.
Put it all together on a pair of pocket doors and you get a picture of perfection. The interior doors are T.M. Cobb F-30 3-panels in fir. Simpson has a similar door here. Check back for trim details at the stairs, crown moulding, and box beams.
