I have exactly this setup and use a Macbook Air with Tailscale to just connect via High Performance Screen Sharing both at home and on the go (when not sitting at my desk, I move around a lot around the house after 3pm or so while I keep my workflow identical)

HPSS works well via 5G, and Tailscale is incredible for the setup as much as the hardware.

Edit: I ended up getting a 15" M5 Air but honestly trying it on a 13" M4 Air was actually superior because when all you care is mobility (since the Studio does the heavy work) its nice just going around with almost no weight / bulk.
