I like the way Voyager does it:
DeltaChat also has a very easy onboarding process: you just put your name, and that’s it. The app creates the password in the background and allows you to switch servers easily. That really helps with onboarding new joiners.
Piefed.zip could be a nice default choice. If there are others you see, feel free to suggest.
Asking “what topics are you interested in” / “what communities do you like” and “what’s important to you” would also help.
Also, “I’m a returning user who did not like the first choice X because of Y” should be an option.
You didn’t like the moderation? Too many defederations? Wrong kind of weird? Bad server performance?
Then try to pick something for them that fixes those problems
This would also require many instances to set out in detail their location, focus etc and have a category system that recognises that.
https://join-lemmy.org/instances has exactly that.
