noob-proof reverse proxy with auth

I am in self hosting for a bit now, have an unraid server and a bunch of services running. Now I want to expose some services through a reverse proxy, but with authentication, preferably google oauth2. I've tried a lot of things, Authentik, Authelia, NPM, and so on. I found everything way to complicated. What I liked the most until now is Caddy with the greenpau/caddy-security module. Very easy config through the caddyfile.... Though the module has to be manually installed after every update of the caddy docker container, thats kind of a turn of for me, since everything else on my server is almost maintainance-free.

You have any suggestions?

.... also this is my first post on lemmy, since I migrated from reddit. ;)
