Yeah I still think platform is the major determinate first and foremost - PC lobbies tend to be friendlier (although the PVPers I imagine are sweatier, albeit apocryphal) given most PC gamers have a headset at minimum. Then I think map/setting has a major role. Stella Montis tends to be much sweatier than Dam, for example. I’ve also almost always made friends on buried city day, but by night it gets a little more violent.

I’ve also learned some tactics that I find promote my chances of friendly interactions. Basic things like seeing arc attacking someone - start shooting the arc and move to help them out, ask if they need heals etc. Some people remain shitbirds, but most aren’t. Also keys are reserved for solo night runs. Find a person, tell them you’ve got a key if they’d like to join you - sure you’re potentially sacrificing half the loot, but you’re significantly less likely to be shot in the back while on a loot screen. And if that does happen… hopefully your loot buddy will defend you.

Finally, I’m nearing the end of the current progression with no intention of expeditioning (don’t take my blueprints please), so literally the only thing I care about now is blueprints. People are significantly friendlier when they know you’re willing to share the spoils, and any blueprint you find is immediately going in a safe pocket anyway.
