At a high level, it doesn't matter. At a lower level, UEFI does have
certain features MBR booting could never have, much of which has to do
with the GUID Partition Table and clearly defined boot executables.

They will only be unbootable if you configure your BIOS accordingly, ie
UEFI only mode. UEFI firmwares (in theory and in at least my machine)
implement MBR booting in a thin compatibility mode, thus as long as you
set your BIOS to both, you should be fine. Just pay attention to your
boot order as usual.

Well, with ZFS, you're not using just a filesystem, you're using an
entire volume manager…

You know I support this endeavour, and you're right.
Remember FreeBSD comes with its own bootloader so no need for GRUB or
anything. I have my FreeBSD VirtualBox VM set up to boot using UEFI.
Can't think of a witty .sigline today…
