And as far as I have heard, Actor and Resilience are the only once that could give you +1 charisma.
Since they all already have charisma saving throws, that leaves actor, which needs you to be proficient in deception and/or performance to be actually useful.
Plus, Resilient: Charisma. Ugh, what a waste of a Feat even if the character isn't proficient in CHA saves.
