That SHOULD allow me to use an EFI boot manager to come up on initial boot, select FreeBSD and the loader.efi (named as bootx64.efi in EFI/FreeBSD) code will then boot the system. I've looked as the 12-RELEASE man page(s) and it's not obvious how you tell the loader to look for the partition and then attach it via GELI (prompting for the password of course) before attempting to boot it; obviously a "load" directive (e.g. geom_eli_load =3D"YES") makes no sense= as the thing you'd "load" is on the disk you'd be loading it from and its encrypted.. .never mind that loader.conf violates the 8.3 filename rules for a DOS filesystem.
