I’ll caution against nextcloud […]

It is indeed rather big and clunky sometimes, but there’s one feature that I really love that I could not really live without. I just tried out Seafile, but I didn’t like the whole “libraries” concept, because it made it very difficult to exclude certain subfolders that I didn’t want on a certain system or to sync multiple local folders to multiple remote folders. I’m using Nextcloud to sync my Documents, Videos, Pictures and Music folders across all of my devices, but I don’t need every single subfolder there downloaded to every single device that I use it on. I also use it to sometimes sync game save files for the ones that I don’t have on Steam. Would you happen to know a better solution than Nextcloud for something like this? I’m currently migrating it from a Raspberry Pi 2 to an older laptop that I have laying around, and I’d happily use a different syncing solution for this, and set up other features that I used (CalDAV, CardDAV) on other containers.

P.S Syncthing looks like what I might need, but I do wonder how I can make public share/upload links with it.
