FreeBSD main on Apple M2 Ultra, likely via use of VM(s): any notes?

Is anyone using FreeBSD [main] on an Apple M2 Ultra (likely that would
be via a VM)? If yes, is anyone willing to comment on the VM used to
host FreeBSD, how it is used with FreeBSD, what works vs. not, or the
like?

A point of interest would be if the VM environment can boot normal
external USB3 media that is also able to be used to boot FreeBSD on
other aarch64 systems (not just booting via VM usage).

(In my environment, even internal media works for booting if just
moved to another system's internals that has the right type of
hardware interface.)
