For upper, I'd highly recommend adding rear delt flys and face pulls at twice the frequency of any chest or shoulder workouts. Most people have overdeveloped front delts and underdeveloped rear delts and that can cause severe imbalances.

Indeed, also lots of over-developed chests which can pull too hard on a back that isn't equally strengthened, causing pain and poor posture
