literally can one-shot almost all bosses if you are using scarlet havoc theurgy fully charged even on Merciless difficulty (already tested it)

Black frost. He naturally gains resistance to his one weakness and he has access to fire + ice tier 3 spells.

Really depends on how you're building them. Any Persona can be good, as long you have a skill set in mind.

But if you're looking for "Fuse it and forget it" kind of deal - Titania is one of my favorites in your level range, excluding what others have already mentioned. Even just working with her innate Ice skills she dishes out solid damage, especially with Concentrate, which she also learns by default (useful if you don't happen to have it on any of your other Personas).
