Looking For Opinions on Docker + Letsencrypt + Reverse Proxy Setup (kbin.social)

I've been running 2 linodes for a number of years now - one has my website (wordpress) on it and one has a Foundry VTT server running. Both are separate linodes, and I use Google Domains to point [site.tld] to the wordpress VPS and foundry.[site.tld] to the other linode.

For a few services I run at home within my own network (Sonarr, Lidarr, Plex, etc.) I've started to use Docker and Portainer, and I like how easy it is to set things up (and remove them if they don't work). I'd like to redo my VPS similarly - I'd like to have a single linode, as a Docker host, and have the main domain point to a Wordpress container, a subdomain point to a Foundry container, and be able to easily add other containers for something like freshrss, etc. My goal is to be able to quickly spin up a docker via a compose file (portainer would be preferred), have it automatically reach out to letsencrypt to get a cert for the relevant subdomain, and have that subdomain point to that docker container.

I've been doing some searching around, and there seem to be a number of options, things like nginx reverse proxy, traefik, etc. and there are a lot of conflicting results.

Does anyone here have an opinion on this or some advice as to what the best option to look into might be?

I use cloudflare and point my domains to its bameservers, which has ssl support ootb. however this does not work for wildcard domains kike *.sub.example.com, which I heavily rely on.

Instead I run a Caddy container with the cloudflare plugin, it's as simple as adding the token and caddy does all the wildcard ssl magic.

Coming from nginx and heavily relying on regex, Caddy is a bit different to set up, but once you dig a bit into it, itčs mostly one-liners.
