Hey if you haven't heard, HAOS has a community add-on for Plex - which is basically docker instance of Plex under the hood.

You might wanna check that out.

I would give priority to HAOS because it removes a ton of setup headaches with other add-ons you might use like Z2M until you establish a proper home lab pipeline.

You'd lose the add-on store if you go the HA docker route and you'd have to manage some networking config within docker if you need to setup other containers to be used with HA - Eg: MariaDB, MQTT Servers, etc...

There's difference in the implementation of quirks and converters. I found ZHA quirks support less than what Z2M already has, especially when dealing with manufacturers like Aqara.

Performance wise both felt similar.

Currently using CloudFlare for two different homes. One is on cloudflared add-on, with Nginx Proxy Manager as the reverse proxy.

The other, CloudFlare tunnel hosted on a docker container in the same network, with Nginx Proxy Manager as well to unify ports for some services.

Both setups been working well so far, ignoring the concerns that the HA frontend may have potential security issues.
