Ratchet and Clank: Rift Apart is a good platformer-shooter. I don't know if you've played any of the other R&C games. They are family-friendly, rather straightforward games with cartooney characters and plenty of humor and action. You can go on Youtube and check out gameplay video (that's a good way to get a sense of whether you might enjoy a game -- check out gameplay video or reviews). Ratchet and Clank on PS4 might be a better intro, or at least cheaper (most PS4 games are playable on PS5).
I loved playing Ratchet and Clank. Great game. Haven't played in a long time.
My son and I played this game when he was younger.
I really think you would enjoy Ratchet and Clank.
