I found a laid back modded Minecraft Java server run by two friends who want more players that are 18+. It sounds like a small group with around 7 to 8 regular people so it feels more like a real friend group than a big public place.
The whole vibe is chill and not competitive. People mostly go on adventures together and build stuff while talking to relax.
They use Discord and also have proximity voice chat so you can run into someone while exploring and just talk like it is normal. The main idea is enjoying the journey and discovering things together and making a world that feels lived in.

I found Jonarchy and it is a survival anarchy server with no rules vibes. It is free to play and it works on Java and Bedrock and even Eaglercraft too.

GG.MINEWIND.NET New Server IPWhitelisted Vanilla SMP For Mature Players

I found a community based survival server called The Eternal Region. It is whitelisted and it is aimed at mature players who want a calmer place to play.
It stays vanilla first but it also has some quality of life changes. Phantoms are off and endermen cannot grief and you get double shulker shells.
The world border starts small then it grows every day and it is currently 5000 by 5000. It also uses Simple Voice Chat so players can talk while playing.
The server focuses on anti grief protection and respectful standards. It sounds like a place for builders redstone players and explorers who want a long term world to invest in.

BoonCraft is a survival SMP server with a small friendly community and players from all over the world. It is mostly PvE and it has a no griefing policy so people can just build and relax.
There is land claim to protect your builds and player warps so you can show off what you made. The server also runs community competitions and challenges and there is usually something new each week.
The economy feels stable and balanced and you can make money in a bunch of ways like player shops jobs quests the auction house voting and selling items. Custom fishing is a big thing too and you can catch lots of fish types and sizes then sell them to the Fisherman at spawn. There are also server wide daily fishing competitions.
If you want PvP you can toggle it and there is a dedicated PvP arena where fights are safe. You keep your inventory you keep your XP and your items do not lose durability.
There is no pay to win and the store is only for cosmetics. You can also unlock free ranks and special perks just by playing.

SoloCraft is a Solo leveling themed Minecraft server that just opened so it will probably be pretty quiet at first.
When you spawn you are right next to a hand built building where you can get your rank and pick your class.
You can also loot a village right away and the server uses Lootr so everyone can get loot from it.
GG.MINEWIND.NET New Server IPMythvale Towny Survival With Siege War

Mythvale is a new Minecraft server I found that is built around a town claiming system. It uses a Towny style setup so players can make towns and protect their land.
There is also a war plugin made for the claiming system with siege battles. You cannot steal land from other towns but you can plunder their money so fights matter without deleting someones whole base.
The world is a custom map made for building and survival. The server is not released yet so it is still in the early stage.
