If you're going to try Authelia and a reverse proxy, I recommend using SWAG. It's a docker container that includes Authelia, nginx, fail2ban, geoip restrictions, and has premade config files for most of the selfhosted software that people run. The config files are especially useful since they include comments that describe the settings you need to change within the services you run, like changing the external domain in Emby for example.
