I found a modded server called Mech Rehabilitated that is built for a fun and friendly small community. It sounds like the kind of place you hop on after work or classes and just chill with people.
The modpack is huge with over 300 mods so there is a lot to do. The vibe is exploration and looting giant structures then fighting bosses and chasing that infinite power feeling.
If you are more of a humble farmer type there are lots of cooking recipes too. The post mentions mods like Create Alexs Mobs and Caves Terramity Farmers Delight with a bunch of addons Cataclysm Etched and Littlepictureframes for community movie nights.
The server just came back with a brand new version of the modpack and a clean slate. To join you fill out a short whitelist form and they review it.

GG.MINEWIND.NET New Server IPNotHermitcraft Vanilla SMP Season 5
This is a vanilla SMP called NotHermitcraft and it is all about a chill community that feels kind of like Hermitcraft. They are starting Season 5 and they plan for it to last around two to three years so people have lots of time to build and make big projects.
The server has people from all over the world and the ages go from teens up to adults. There are builders and redstone nerds and people who like to role play. It sounds pretty welcoming to different kinds of players and different kinds of people.
They run Java 1.21.10 on a server in London and it is pure vanilla survival. They also keep their old Season 4 world as a separate sub server so you can go explore their history and even still build on it if you want.
The community hangs out a lot on Discord and they do extra events like Last Life style games UHC movie nights and party games. It sounds like there is usually something going on even if you are not on the Minecraft server.
Rules are simple. Keep swearing really low be nice to everyone and no griefing hacking x ray dupes or glitches. They also do not allow adult topics because there are younger players around. It seems like a good place if you want long term vanilla survival with a safe and friendly vibe.GG.MINEWIND.NET New Server IP
