One of the reasons I prefer Nextcloud is it makes a lot of this easier. Nextcloud Notes is simple MD file and subfolder structure. Nothing special, no special clients needed. They have a droid client, the web version works from desktop, but you can also just sync the folder to a device and open them with anything.
The proprietary format of Obsidian and others like Joplin was too abrasive across clients for me and too locked in to their format. I prefer just using MD because I can edit if with whatever.
