I found that the resilio mobile app would use up a lot of battery at night (sometimes about 10% an hour).
Syncthing was better for that, but would sometimes just stop updating on a phone. I would check and it would have not been syncing for weeks and be signed out of the web UI.

I use Obsidian as a OneNote replacement because it’s built around markdown, which is just a a text file that includes structure and formatting.
I don’t use their subscription syncing service, just sync files to my own phone and server. Obsidian is great for organizing, but I can still read all the files as text.
