Thanks for they reply, and link, Andrey!
Well that confirms it. FreeBSD, unlike other OS implementations, will not
permit booting your chosen "version" via EFI. That is; not without dropping
to the loader prompt, or changing the status of slices, or boot entries prior to
reboot. :(
Looks like I'll need to install a third party OS, or bootmanager to use FreeBSD.
Sigh...

There *may* be hope in the future (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207940)

Thanks again, Andrey. Greatly appreciated! :)
