It looks like current versions of FreeBSD support Linux containers and podman. Can anyone speak to the experience and performance there?

Depending on what you are doing and what you wanna run you don't really need it. For most use cases, just `pkg install -j` (-j is for jail) what you want. Or just put the Linux binary (prefereably the musl/alpine one) in a thin jail it usually works.

I haven't tried podman in FreeBSD yet because from what I understand you can only run it as root right now, so it kind of defeat the purpose.
