OneDrive? WSL is already in Windows so you don't really need to sync anything if you think about it. Each of my devices kind of play a role and they don't need to all be whatever you would consider synced. Edge syncs... OneDrive shares data... What else do you need to sync?

I'm not dismissing you I just think you need to come up with a more cohesive definition of synchronization of blank. Do you want your terminals to have their histories synchronized? Do you want the entire hard drives to be the same? Do you want your web browsers settings to be the same?

You could even use git for something like this. And you could just pull repos locally for projects that you're working on and just synchronize them between computers that way and just host a local gittea or something.
