I have had broadly the same use case - small scale file sync (text notes, some documents)
If you want to save some cash, I can recommend Syncthing. You don't need to host a server for it unless you want to - it is peer-to-peer with all devices you want to be linked via their discovery servers (you can host your own as well).
I used to host my own Nextcloud for about 3 years, moved to Syncthing a few weeks ago, pretty happy so far.
