I found a community based survival server called The Eternal Region. It is whitelisted and it is aimed at mature players who want a calmer place to play.
It stays vanilla first but it also has some quality of life changes. Phantoms are off and endermen cannot grief and you get double shulker shells.
The world border starts small then it grows every day and it is currently 5000 by 5000. It also uses Simple Voice Chat so players can talk while playing.
The server focuses on anti grief protection and respectful standards. It sounds like a place for builders redstone players and explorers who want a long term world to invest in.
