You can read this very long list of recommendable co-op titles for game nights (online or couch) here:
https://www.reddit.com/r/NintendoSwitch/comments/dlx6od/a_very_long_and_updated_list_of_recommendable/
Should help you on your quest!
I got No Heroes Here from this recommendation list yesterday, and it was a nice online cooperative game.
Shame I was not able to get Overcooked 2 while it was on offer.
