My app of choice is AntennaPod, mainly because its the best app I've found on FDroid.
Recently I've been listening through Newbie Star Trek, just because I really enjoy TNG and its nice to hear the discussions about it. I also listen to Security Now(since I do cybersecurity), the citizen's guide to the supreme court, and no bullsh!t vegan.
This is pretty similar to what I do. Except I just use ngnix to forward http requests through the wireguard tunnel based on the host header. Although theoretically you could also use the TLS server name.
I wonder if you could do this as a community project. Everyone could pitch in to cover the cost of the VPS and join their server to the VPN for small self-hosted projects like a website.
