I found a modded 1.20.1 survival server that is whitelisted and meant for adults. It just started and it is super small right now with only two players.
The vibe is chill and cozy and they want long term players who like a close knit community. People are trying to build something worth while together and keep it small.
It has stuff like food animals building and exploration. They also say it runs well even on potato PCs. They are picky about who joins because they do not want any weirdos.
