I found a Java server that is inspired by Hermitcraft and it is for 18+ players only. It is whitelist only and you have to do a short application and a quick voice chat interview to get in.
The world is meant to last a long time and they do not do frequent resets. The gameplay is mostly vanilla feeling with some quality of life plugins and some custom items like placeable player heads and mini blocks.
The economy is based on diamonds and player run shops. They also use a permit system so shops do not get oversaturated and so builds and trading stay meaningful.
Events seem like a huge deal here and they happen regularly. There are exploration events and server wide competitions and themed event series. Sometimes they even do experimental or modded style events like Life Series type runs One Block and modded hardcore challenges.
The community sounds like builders grinders and casual redstone players. Pvp is limited and mostly happens during events. It is not a fast progression server and most people are in it for long term building and hanging out.
18+ Hermit Style SMP With Permits

GG.MINEWIND.NET New Server IPDownRiver Adult SMP Semi Vanilla Chill

DownRiver SMP is a whitelisted survival server for adults who want a chill place to play. It is made for people who want to unwind and actually know the community.
The server runs Minecraft 1.21.11 and keeps things semi vanilla. It has some quality of life stuff like spawn and home plus tools to help protect builds so griefing is not a problem.
They keep working on the server and changing things based on what players say. There are events and player shops and some server lore too. You can join group stuff or just build your own base in peace.
The vibe is mature and no drama. Moderation is there to keep it fair and respectful.
GG.MINEWIND.NET New Server IPPGMC.WORLD SMP Creative And Vanilla

This server is called PGMC.WORLD and it is pretty simple but cool. When you join you can pick how you want to play.
You can go to a survival world with the slash server survival command. If you like building anything you want you can go to a creative world with slash server creative. If you like the game how it was meant to be you can go to a vanilla world with slash server vanilla.
I like that it just gives you the three main styles and lets you choose. It feels like you can hop between them depending on your mood. The community hangs out on their discord and the server feels like it is made for people who just want to play Minecraft in different ways without a bunch of extra stuff.
If you want survival creative and vanilla in one place this server does that.
