So far as I've been able to find out, HA is only installed as an image
on the SD card (using the RPI Imager), rather than manually installed on
an existing Pi image (e.g. apt install ...), so that means that the Pi
can only be used for what HA allows you to do.  Therefore, one downside
(for me) with HA is that I don't seem to be able to gain SSH access to
the PI.  I can access it via the web interface, and I can install a ZSH
shell on it, but that is in (I think) a Docker Container.  What I would
like to be able to do, which I can with my other Pis, is to run regular
health check stuff, CPU temp, free memory, free card space that sort of
stuff.  I can do that from the Docker Container, but I can't set up a
cron job to do it, and I haven't even tried getting it to email me a
daily summary.

 HA can be installed in several ways.

I had no idea why I chose Domoticz over HA, it was a few years ago, but you present a compelling argument.
My rpi4 Domoticz install is a 12 line docker-compose.yml.
I already had MQTT.
Domoticz works, lets me switch things on and off, immediately or scheduled, and provides me with historical usage graphs. Which is all I really want.
Dunno if it relates to you, but I had a similar SSH problem.
I had a Gitea Container (a pretty UI git repo manager) needing to reserve the standard SSH port for git to work, this took over the host rPi host standard SHH port. My solution was to assign the Gitea container its own LAN IP address using a Docker Macvlan network drive, thus the Gitea container and the host rPI could each use the default SSH port as they had distinct IPs.
