> cgroups, and I’ve never saw any useful docs for how to use them other than “just use systemd, man, it’ll do it automagically for you”

You and most people will probably already know this, but of course you can also use cgroups without any special software by manipulating the files and directories in /sys/fs/cgroup (or wherever else you mount the cgroup2 filesystem).
Everything is documented at https://docs.kernel.org/admin-guide/cgroup-v2.html.

However, I don't know whether this helps in the context of libvirt and Docker. I'm not familiar with them and don't know what their requirements are.

I did in fact not know that; I hadn’t researched into cgroups in more detail.

Much appreciated.

You might want to have a look at the cgroups(7) manpage to get an introduction to cgroups in general.
