I just recently set up a reverse proxy with Nginx Reverse Proxy, and Cloudflare. I pointed my domain to my home address with Cloudflare (they have dynamic DNS capability), then set up NRP, to forward traffic by subdomain. The nice thing about the reverse proxy it is I can bind a subdomain to an ip:port on my local network. Like “music.!MYIP!.com” goes to my Navidrome instance “LOCALIP:4553”. This allows me to close unnecessary outbound ports.

Um, .wav is a lossless format. It’s just raw PCM with no compression. An upscaled FLAC from a lossy source is not lossless, even though it’s stored in a lossless compatible format (FLAC). A properly encoded and compressed MP3 file will sound very close to the lossless source, but when procuring those lossy files from third parties, you rely on whoever compressed them doing it properly. I prefer to store my music repository in a lossless format, and stream/sync in lossy.
