I found Lumenor SMP and it runs 24 7 with a custom vanilla style world. It is on 1.21.11 and it also lets newer clients join with support for 1.21.4 and up.
It works for Java and Bedrock and even cracked players can join. The big idea is the role system where you can pick Passive if you want peace or pick PvP if you want chaos so different players can still play together.
The world has custom biomes and huge structures like ancient temples. There are rewards to find and it feels like it wants you to keep exploring.
There is player driven trading that is more like villager style trades and not a normal money shop. There are also PvP and Passive arenas where keep inventory is on only in the arena so you can practice without losing stuff.
It has custom armor trims that give small buffs and the Nether is made to be really challenging. They also say there is strong anti cheat to keep things fair. The server is hosted in Germany and the staff is from a bunch of countries so it feels pretty welcoming.
Lumenor SMP Semi Anarchy With Roles
NO WHITELIST CHAOS PVP GRIEF SERVER
I found a public Minecraft server that was made because the owner got super bored and wanted anyone to join.
There is no whitelist so you can hop in anytime. PVP is allowed and griefing is allowed too so it is pretty much chaos and you should expect fights and wrecked builds.
If you want a server where people can just jump in and do whatever then this one is that.GG.MINEWIND.NET New Server IPModded Feel Vanilla SMP Worldgen
Vaulted Vanilla is an SMP that tries to feel like modded Minecraft but you still join with a normal vanilla client.
The world generation is heavily changed with new terrain and big structures to explore. The dimensions are overhauled too using Terralith Incendium so the overworld and the Nether feel way more interesting.
It also has quality of life plugins and data packs plus waystones and proximity voice chat. There are custom items and SlimeFun4 for more stuff to do. The server has a subtle economy and fishing competitions to keep survival from getting boring.
It is on version 1.21+ and crossplay is enabled. They are a newer community and they want feedback while everyone builds it up together.GG.MINEWIND.NET New Server IPCozy Vanilla Survival With Kind Players
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.GG.MINEWIND.NET New Server IPNEW SMP JUST DROPPED NO RESETS
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.
The server keeps the vanilla survival feel but adds extra progression systems you can choose to use. There is a player run economy with shops trading jobs and an auction house so you can grind money and become the server merchant.
It also supports cross play so Java and Bedrock players can play together. PvP is optional and there are risk zones if you want higher stakes while other players can stay more peaceful.
The community is described as chill and welcoming with room for teamwork and also competition. It seems like a good fit if you like building trading exploring or planning big projects.GG.MINEWIND.NET New Server IPFresh Semi Vanilla Season Server

It is running on 1.21.11 and it is almost completely vanilla. The only changes are anti x ray and some admin stuff so it stays fair
There is a register plugin so cracked players can play and their names do not get stolen
