I gave up with all modern Remote desktop and switched back to vnc and its been working flawlessly. I use tailscale to make the vnc ports accessible to my private network and I'm able to just connect via tightvnc. Remote desktop was only ever complicated because you had to open ports and make your machines accesible online, and with tailscale solving that whole mess for me its as simple as connect to this ip and its done. Thats all the paid options ever took care for you, the core functionality hasnt been changed in forever, unless i guess you care about extreme low latency which products like parsec offer.
