Correct. That' s definitely the source of the booting issue.

EFI is able to boot any FreeBSD box for a while.

The main issue is that the legacy way to upgrade these /bootcode and 
partcode/ not only does not work, but do bad things.

# gpart bootcode -p /boot/gptzfsboot -i 1  ada0s1

will install an old and inappropriate /partcode/.

IMO,
'gptzfsboot' should be sweep off  along with 'boot1.efifat' ( by calling 
'make delete-old') or be built with the right 'BOOTx64.EFI', which 
actually is`/boot/loader.efi` .
