I expect that should reference ( unsure for EFI vs. efi ):

cp /boot/loader.efi /boot/efi/EFI/freebsd/

The point being to copy from ZFS/UFS to the ESP
for environments that use EFI\FREEBSD\LOADER.EFI .

-t msdos vs. -t msdosfs ?

So far as I know /boot/efi/loader.efi is never the right
path for ZFS, UFS, or the ESP under the msdosfs ( given
mount -t msdos /dev/ada0p1 /boot/efi ). /dev/ada0p1 would
contain an EFI directory that has more substructure.

After the install world, cp /boot/loader.efi /boot/efi/EFI/BOOT/
should work as well. ( /boot/loader.efi having been updated in
ZFS/UFS. )
