As I have basically all devices connected to my Nextcloud instance, I simply use that. I don’t have any “time-critical” file transfers though.

That sounds like a job for… a spreadsheet.

There are other options available, especially if you just want file sharing. Pydio Cells, Owncloud Infinite Scale, a custom WebDAV setup, etc.

What are your main goals? Do you want all data on all machines, or all files on a central server and only sync what you want?

How did you set up Syncthing on your laptop?

Works well for me, although with Docker. The labeling can be a bit non-intuitive at first, but it’s really solid.

Also, I simply love autodiscovery.

Wait, you update productions systems without running a staging environment? Or even checking the update notes and your installed apps? Also no backups? What kind of business are you running over there?
