Syncthing is great. I'm closer to the poster you're responding to -- I tried Asahi Linux and liked it, at least when I ignored the "Mac users will probably like GNOME more" and switched to KDE Plasma (this Mac user, at least, thinks it's way better), but still ended up back on macOS Tahoe despite having a myriad of nits to pick with it. But when I was playing around with it, I set up Syncthing so I would be able to keep working on documents on the Linux laptop, other Macs, and the iPad, and Syncthing worked fast and basically flawlessly, better than either iCloud or Dropbox in my experience. I may eventually set it up as a local sync solution between the Macbook Pro I'm using for everything and a Mac Studio that's become my home server.
