How do/would you use it over various systems? What's the best way to cloud sync this? One might have to use it on work machine with restrictions around installing apps.

As long as auto-revert-mode is on (so the editor notices synced changes from other devices), you can sync it using any file storage service: Dropbox, iCloud Drive, Resilio Sync, etc.

I use org mode and sync with a git repository. Thoughtfully emacs and git are both approved.

Do you have any hooks setup to automatically commit/push if file changes are detected?

[Forge36]

I have a server hook to make a commit (which causes the push to fail) if I forget to manually make one. I have F10 in emacs setup to commit and pull to local. Local is also setup to rebase on pull.
