Everybody is a little different. For example, I rarely do any kind of shoulder presses myself because I don't really get anything out of them. On the other hand, my shoulders seem to respond the best with any kind of raises (front, side, rear, cable.) Maybe your shoulders are the same way! All you can do is try and see what they respond to the best. Depending on the degree of the incline of the bench press, you might get plenty of shoulder action that way also, even though the exercise isn't primarily for the shoulders. LOL When working shoulders, just remember to have strict form, work them hard, get plenty of protein for building new muscle, and get plenty of rest!
Any other muscle groups and exercises, you are ganna have to be more specific. Good luck
If you build it they will come
