Escape Academy or similar type of escape room/puzzle games might work.

Slay the Spire 2 has a good co-op option. And technically any digital boardgame (ticket to ride for example) would meet your vibes.

Maybe a little more intense, but Rayman Legends/Origins are pretty cozy.

Any of the Lego games would probably work.

Peak has an “easy” setting that just makes it a goofy teamwork based game.
