Joplin is excellent. You can run your own sync server and not rely on cloud storage at all (there's a docker image - very simple to set up). It also imports and exports a hierarchy of folders/markdown files, so on- and off-boarding are simple. For many years I used plain old markdown files and either git or syncthing to ship them around, but the editing and viewing experience was never great, and sync on iOS wasn't exactly seamless. The other big benefit is cross-note search. Previously I had to rely on the editor I was using - which was fine on a desktop with VSCode, but nonexistent on mobile.
