I found a Java survival server called JSMC that started because the owner got tired of the same friend group worlds dying after two weeks.
This one is meant to keep going even after the Ender Dragon. It has been on the same world for about 8 months with no wipes and no resets. The pace is slower and it does not lean on gimmicks.
People focus on builds that are meant to last and a lot of the map is set up in themed areas so it feels connected over time. Not everyone stays forever but the players who do stick around tend to stay for months.
