Tailscale is great in that config is super simple. Downsides tailscale ssh has to be called at launch if you want ssh access over that network… Could be a benefit for security…however its a tailscale specific ssh and not everything is available.
Data servers moved to the USA a few ears back.

Wireguard is more setup, but a better (self host option ). There is also Headscale if you want to selfhost a tailscale type server
