Cozy MC is a vanilla survival world on hard difficulty and it feels like singleplayer but with other people around. The whole point is inclusivity and kindness so it is chill while still being real survival.
There is no fancy spawn or lobby stuff. People just play in a trust based world and it often has around 40 players online.
Stealing and griefing get you banned. They also have tools to fix damage and tools that let players check container transactions so theft can be found and reported.
PvP is only allowed if both players agree. You can still find friendly duels happening sometimes.
When you first join you cannot break blocks or pick up items until you type commands to read the rules and learn the steps to start. Verifying in their discord can also help you get going faster.

I found StableSMP.ca and it is a long term survival server where players shape the world as it grows. It starts fresh and it is meant to keep going with no resets so your builds and choices can actually matter.
