Yup! Mostly symfonium since i mostly use my phone for music. Started using feishin recently for desktop use and have been really impressed with it. I can recommend both!

for music both jellyfin and navidrome are subsonic API compatible for use with mobile and desktop apps (like symfonium and feishin). Some people choose to just use jellyfin instead of a dedicated music service. Personally i still run navidrome for music. I give some thoughts on that here

This is what i do. Have certbot running every night, and it’ll auto skip if it is too soon to renew. If renew is successful then it’ll deploy. Pretty much set and forget it.
