Nginx is pretty simple to run as a reverse proxy. Caddy is even easier but not as scalable.

HAProxy looks intimidating at first but it’s pretty easy and very scalable and performant. Wendell from Level1Techs has a nice writeup on their forums

Oh, there’s also Nginx Proxy Manager that is very clean and very easy to work and manage with it’s nice web UI

Frigate and a Coral TPU work amazing. I’ve had them and Home Assistant setup for the last year or so and have been quite happy.
