Maybe I'm just doing it wrong. I've just found LXD to be lacking as you can't live transfer it to a different host. It is also slower than Docker and Podman and I was unable to get docker running in a unprivileged LXC container. I think it should be possible to run docker in LXC but by the time I spend the effort is is more secure and easier to use a full virtual machine.
Maybe I should revisit the idea though as it seems like many people stand by it.
