Do you have friends or family in your home country that will run an AppleTV box with Tailscale for you as an exit node?
I can't get into work from a non-US IP, but I can Tailscale back to my house and it works just fine. I even gave my in-laws (who live several states away) an AppleTV box running TS just to have another endpoint if for some reason the power goes out at my house while I'm gone (rare, but happens).
What is this AppleTV box running TS that you speak of? Sounds awesome.
Why do you need an AppleTV box and Tailscale for that? Use any PC (even a Raspberry Pi or any cheap "thin client") with Wireguard and you remove Apple and Tailscale from the equation entirely while keeping your setup 100% self-hosted.
