I found MyChunk and it is a global creative server made for people who really like building. It tries to stay stable and lag free so you can focus on your projects.
The main thing is the MyWorld system where you get your own private space. You can control permissions and choose who can build with you.
WorldEdit is free to use and it is not stuck behind a paywall. There is also advanced grief protection so your builds stay under your control.
It supports Java and Bedrock and it runs on version 26.1 or close to it. People join to share builds and show off their creations.
