If you’re into souls-likes, try “Stranger of Paradise”
Its fantastic, nobody has heard of it for some reason. I played this last year with a friend and it was really fun (if you’re into that playstyle)
Darksiders Genesis was also very fun with my little cousin, more hack n slash, one player gets to be pure meelee and the other half meelee half twin stick ranged.
Sniper Elite (4?) is pretty good as a chill co op FPS mission progression game.
Otherwise, probably any survival craft will do, you already played a few. I enjoyed Valheim and Planet Crafter and wish Subnautica had Multiplayer.
