My pipedream is to have a containerized desktop environment like this that outputs directly to a physical monitor over HDMI/DP without needing an X server on the host machine. So far I haven't found any clear answers on whether that's possible at all.

I feel I've been nerdsniped or, some other term for your quest being contagious, I also now need to know if this is possible I found a thread from someone who seems to know what they're talking about saying it's not going to happen "on your hardware", but doesn't mention what hardware might be required https://forum.level1techs.com/t/can-intel-integrated-gpu-output-to-an-external-monitor-via-a-usb-c-displayport-cable-when-vm-uses-nvidia-discrete-gpu-on-another-external-monitor-in-a-muxless-optimus-laptop/194826 https://forum.level1techs.com/t/can-intel-integrated-gpu-out... Edit actually reading that link again it sounds like a USB adapter worked right away as a monitor for the VM and the OP is asking how to prevent this ! So seems you just need to enable GPU passthrough, and a USB HDMI will appear to your VM ? Will have to try this later today

I can only answer for NVIDIA, as that was the platform we developed on, but it should be possible to encapsulate the X11 server within the container without starting an X server on the host machine, and then plug in to the monitor you designate. I can answer further if you are satisfied with the directions found within https://github.com/selkies-project/docker-nvidia-glx-desktop https://github.com/selkies-project/docker-nvidia-glx-desktop. It has a lot of effort to NOT require a monitor, but it should also work with one.
