Logseq + Syncthing has been working quite well. Logseq is well maintained, has a fully functional Android app, and a thriving plug-in ecosystem. I have been using the combination for a year and it's an excellent long term solution.

syncthing is not good for me, I don't like using third parties

Syncthing is one of the only sync solutions suggested here that doesn't use third-parties.
