I've recently discovered systemd-nspawn which is an alternative to LXC, builtin and integrated into systemd. Much lighter than full VMs and it's quite similar to Solaris Zones and FreeBSD jails. One way to use it is to extract an OCI (Docker) image to a path, that way you can reuse the container tooling provided by Docker, Podman et al. I've barely touched the BSDs and it's been a few years since I last used Solaris so I can't make much of a comparison as a user myself.
