I basically have the same setup, using nextcloud notes. The notes aren't in plaintext, they are in markdown. Joplin can use nextcloud has a sync backend. There are also other note taking apps that can use nextcloud has the sync backend but in the end I wasn't happy with anything. Going to test drive Obsidian and dendron.so to see how they go.

I'm using https://play.google.com/store/apps/details?id=it.niedermann.... on my phone. It's not super fancy, but it works well. I might try out Joplin sometime, but I'm pretty happy with what I've got.
