I've been self hosting traditionally in debian, but I would like to be able to add services easier using docker. As such, I'm looking to move to a container based architecture.

One place I struggle is that I can't seem to find a good container where the default image supports ACME to support Let's encrypt for automatic cert renewal.

For Nginx, I would have you build my container. HAproxy ACME support seems to be a shell script.

Any suggestions?

It's not Let's Encrypt, but I've been happy with this Cloudflare-flavored ACME through Caddy.

I really only use it for my local-hosted stuff that I don't expose to the web. So, when I'm at home, https://radarr/.[mydomain].com resolves to 192.168.1.145:7878. That sort of thing...
