There is no ESP present in the guest. Instead there is a
"type: freebsd-boot" partition for which one of the likes of:

# ls -lodT /boot/gpt*boot*
-r--r--r--  1 root wheel uarch  62139 Apr  7 15:55:46 2024 /boot/gptboot
-r-xr-xr-x  1 root wheel uarch 109568 Apr  7 15:55:46 2024 /boot/gptboot.efi
-r--r--r--  1 root wheel uarch 176062 Apr  8 01:15:54 2024 /boot/gptzfsboot

would be in use. None of the 3 support the combination EFI and
ZFS-for-root-file-system. The only one of those 3 supporting zfs
is: gptzfsboot
It is documented to only supports old style BIOS context:

"man 8 gptzfsboot" indicates "gptzfsboot is used on BIOS-based
computers to boot from a filesystem in a ZFS pool".

gptboot and gptboot.efi only support UFS according to their man
pages.

If EFI is in use, then the ESP-ish partition is not from the guest
context but from some place else --unless the man pages are wildly
wrong about what is supported for the gpt*boot 's.
