Btw @Sidd to answer your question, Kakashi doesn't use every powerful jutsu he knows because he doesn't feel the need to master them since they wouldn't fit in his regular battle style. Just like he doesn't use the Rasengan.

In terms of asking why he doesn't learn Shadow Possession, it's probably because it takes up a lot of chakra and he doesn't have a ton to spare.

While I think he could copy any Hiden, I think that unlike regular jutsu most Hiden are odd enough that he'd have difficulty using them in battle properly (unless he has seen em in action a lot) Don’t you need hand seals for Chidori/Raikiri? Also could Kakashi copy calorie control and use without dying with his current physique.
