For the RPi4 UEFI/ACPI based boot context . . .

I grabbed a loader.efi from:

https://artifact.ci.freebsd.org/snapshot/head/r362017/arm64/aarch64/base.txz

(the closest to -r362008 that was available for aarch64).
Substituting it as EFI/BOOT/BOOTAA64.EFI into what I'd been
attempting boots with and got (no other updates, so not
expecting a complete boot):

Looks like loader.efi vintage problems were what
previously stopped the boot much earlier (no
loader output back then).
