For option 1, the NAS could even be an old router flashed with OpenWRT or a cheap $80 mini PC that has a portable or internal 2.5” disk attached.

Seafile ‘scrambles’ files and doesn’t make them available to other applications on the host, which I don’t think OP wants.

Nano is more like fast food. It’s easy and convenient, but it makes you feel a little guilty and dirty afterwards.
