Get your own VPS server (VPS in EU/US with 2GB of ram, 40GB of disk space and TBs/month of traffic go for $10 a year, it's that cheap). Never get anything in the UK and even USA is weird. I'd stick with EU.
Install your software (wireguard + obsfuscation or even tailscale with your own DERP server)
Another simpler alternative is just `ssh -D port` and use it as a SOCKS server. It's usually not blocked but very obvious.
