Apathesia is a whitelisted SMP that runs on 1.21.11 and it is modded Fabric with Geyser so Java players and Bedrock and console players can all join.
The main vibe is that it is fully against money stuff. There is no economy and no crates and no ranks and no FOMO tricks. They also say no resets so your work is not getting wiped for hype.
The mods are server sided only so you do not need to download anything. The world gen is upgraded with Terralith Stellarity Towns and Towers and Incendium so exploring feels way less boring.
It also has QoL commands like rtp in a 20k radius plus home tpa and spawn. There is trade and mail and chest locking. They also have small cozy extras like crouch hearts sit hat and even chess.
They say no world border and no over moderation. Trading stalls are player run and still with no currency. All ages are welcome but you have to act mature and any hate speech harassment or cheating gets handled right away.

Bee SMP is a small 18 plus Java server that runs on Fabric and it is starting back up with a fresh world on February 11th.
It is modded and the season changes a lot of vanilla stuff like structures fishing farming exploring and building. I saw big mods like Create Farmers Delight Friends and Foes Gone Fishing Patboxs brewery Sea Life Serene Seasons SVC and Travelers Backpack. There are also smaller mods that add extra sounds particle effects and other immersive tweaks.
The community likes doing events building projects and game nights. Being able to use voice chat is preferred.
