I found UneasyVanilla and it is a long running vanilla survival server that has been going since 2020. The world has never been reset so the map feels lived in and kind of scary.
It is raw survival with no teleport commands no economy stuff and no land claiming. If you see a base or a trail it was made by real players and you can tell people have been everywhere.
Griefing and raiding are allowed so you need to be careful. Hacking and cheating are not allowed and the staff mainly focuses on stability and fair play.
Spawn is totally wrecked with years of damage and lava casts. Getting out of spawn is like your first mission and then the world opens up for building exploring and fighting. The server runs on version 1.21.11.
