This exactly! I didn't put it in the OP but yeah, more mortal problems would be a bit better. Sure, like someone else said, demonic possession is possible in this universe, but it isn't exactly common and it very much feels like every single character in the party is a protagonist. It's like having the entire cast of a story be a chosen one (Divinity OS2 did this, but the plot revolved around that rather than something entirely different (tadpole)).
It true DnD fashion - every PC is a protagonist. When you play on the tabletop with three other players, you don't just have one protagonist - everyone is one. Though you don't control their dialogue responses to your created character, you otherwise are controlling the entire party.
