I found a server called Aethron and it is a Java 1.21.11 Towny survival server. It is still pretty new and it has been up for about a month with around 15 players so far.
The world feels more wild because it runs datapacks like Terralith Incendium and Nullscape plus more. You can explore and build towns and help shape how the place feels while it is still growing.
People are active during the day but sometimes it gets quiet. It seems best for players who want to be part of the foundation and not just lost in a huge crowd.
