This is a semi vanilla SMP called WhimsyWillow and it feels pretty cozy. The server is still kind of new so there is a lot of fresh land to explore. The terrain generation is really cool and there are over 100 different biomes so it always feels like you are finding something new.
The community is small but the people seem nice and pretty chill. They also use optional origins so if you want a little twist to your gameplay you can pick one but you do not have to. The server border keeps expanding so even old players get new places to explore.
There are rules against griefing and some extra rules too so it stays a safe place to build and hang out. You can basically go crazy with your ideas without worrying someone will ruin it.
The owners keep adding new content and they run events to make the server more fun and keep it community based. To join you just apply through their discord with a short application and they really want you to read the application carefully.
