I use two note taking apps, Obsidian and Nebo, each for their own use case.

Obsidian has everything your needs are, you can setup syncthing to sync your notes across multiple devices. Everything is a .md file and organized using folders and it has great plugin support. Though ability to publish from inside the app is locked behind a subscription. You can always use pandoc to just convert the md files, there probably are some plugins that try to do that. Also i love how lightweight it is.

Second is Nebo, Nebo is for handwritten notes usecase. This isn't something many people really have a usecase for, But Nebo has AWESOME handwriting -> searchable text conversion, specially for Math! And publishing things is as a easy as clicking publish. And it has google drive/drop integration for sync (I'd rather use syncthing but the android app doesn't expose the stored files).
