I found a small laid back Minecraft server run by a few friends who want more people to play with them.
It is modded and the mod list is curated so it adds lots of stuff like new monsters and weapons and armor plus mounts and resources and furniture and cosmetics.
Even with the mods it is built to run well. It uses Fabric and it is meant to be easier on lower spec PCs.
The main vibe is exploring and building and discovering things together. It is not competitive and it is not for people who only want to play solo.
People talk in Discord and the server also uses proximity voice chat so you can run into someone and just talk while you explore or build or team up.

Lumoria is a chill modded SMP for Java 1.20.1 on Fabric run by a couple friends who want more people to play with.

GG.MINEWIND.NET New Server IPA Survival World That Never Resets

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.
