Not every platform allows this, primarily due to being "certified"
by MICROS~1. Maybe in the future, UEFI will be the only available
system, and it will be locked down to actively prevent booting
anything that "doesn't fit"...

GPT shouldn't be a problem when you use FreeBSD only. In case you
want to multi-boot, using GPT tends to introduce more trouble and
Allow me to repeat pointing at the following summary of how to
properly initialize disks:
You will also find suggestions on how to deal with UEFI booting
on that page.

Problematic for modern devices with no optical media reader. And
sometimes, booting from USB DVD drives also doesn't work as intended.

Only if you want to boot more than one OS. :-)
Sidenote: If you want to only use FreeBSD, you can also use the
dedicated disk layout (no GPT or MBR at all). Keep in mind this
is the "traditional" way of partitioning a disk, whose concepts
were introduced before the PC era. Interoperability with Linux
or "Windows" is definitely out of scope here. ;-)

Yes, this is important to remember.
