RDP has been the default on Fedora since version 40 (or was it 41?) and it has been a true joy to use! Remoting in to help family and friends has been as simple as set and forget, and very secure since I use it via my VPN (no public endpoint).
I use Remmina to connect though, not GNOME connect, as Remmina is more configurable.
Yeah, that is what I would have done. Check out Tiny10 and Tiny11, which is stripped down, but totally functional Windows versions that is perfect to use as base images for a VM. I used the default VM/QUEMU app that ships with Fedora, called Box (I think?). But you could install VirtualBox as well.
