I found a server called MinecraftOffline that runs on version 1.21.11 and it is made for people who want a world that sticks around.
The map is permanent so it is not getting wiped all the time. It also uses a custom plugin suite so it is not just plain vanilla.
It is based in Finland so it should feel good for players in Europe. The server also says it runs on reasonable hardware and that helps keep things stable.
