That could very well be the case.

Hmm, I was hoping that the pmbr / gptboot would work "both ways".

No, I haven't found any place to do that.
Before I installed FreeBSD on this SSD (before it was partitioned with gpart) it showed up in
the BIOS under "hard drive". (Other choices are "removable drive"
Now it shows up under "EFI device", and doesn't show up under "hard drive".

Yes, after a bit of searching I agree with you.
If anyone knows of a EFI capable boot loader for FreeBSD, I'm willing to try it.
Rather that, than having to deal with grub, elilo or the other stuff.
