Sunset Retreat SMP is a seasonal survival server that feels really calm and cozy. It is made for players who are 18 or older and want a place to escape real life stress and just play Minecraft.
The server is vanilla plus. That means it still feels like normal Minecraft but it has a few quality of life features. It has voice chat player and mob heads a live map and it works for bedrock players too. It also uses a diamond economy where players make shops and trade with each other.
The community is whitelisted and focused on chill mature players. People here seem friendly and welcoming and it looks like a good place to meet new friends and hang out. The owners are active and they actually play on the server and keep things updated and managed.
If you want a relaxed survival world with a small adult community and just enough extra features to make things smooth this server fits that vibe.

GG.MINEWIND.NET New Server IPNoHeart SMP Lifesteal Combat Without Anarchy

I found a server called NOHEART SMP and it is a modded survival SMP with a big combat focus. It uses a modpack that includes Enchancement and Arsenal by doctor4t and it also has Lifesteal so fights actually matter.
It is not anarchy though. Griefing is not allowed and stealing is not allowed so you can build stuff without it getting ruined.
It is not scripted but you can make your own lore if you want. When it was posted there were 7 members and 20 slots total so it still feels small.
GG.MINEWIND.NET New Server IPFresh Vanilla Lifesteal SMP No Mercy

I found this vanilla survival SMP that runs on a lifesteal system where fighting actually changes your health. If you kill someone you steal one of their hearts. If you die you lose a heart and when you run out you get eliminated.
PvP is on everywhere with no safe zones and no protection so you are never really safe. The world is huge at 150k by 150k and it is meant to feel untouched and vanilla.
It is also trying to stay fair with no pay to win and no overpowered kits or handouts. People will make alliances and then betray each other when it helps.
There is a statistics command so you can track kills deaths streaks and playtime. Chat is interactive too so you can show the item in your hand to everyone. The server version is 1.21.11.
