What games have fun PvE co-op with strangers?

Looking for more games with fun co-op online with strangers. Here are a couple examples of games I've had a great time online with:

• Elden Ring / souls games: co-op is optional, but provides a major advantage. minimal communication e.g. no text or voice chat helps keep interactions friendly, matchmaking is easy, encounters are typically short.

• Diablo 3: good LFG matchmaking, co-op is optional but gives a big advantage in the form of faster clearance & higher drop rates. Generally low difficulty means people are less toxic.

PC preferred but I'm open to console games as well.
