right before the rootfs (monted on /), what made little sense to me. I said "no", making the system, for the time being, unbootable.  The installation completed except for that step.

I noticed that too, and did the same, but it didn't result in an
unbootable system since I had the EFI partition already set up from an
earlier install (which I don't recall wanting to create an EFI
partition, but I may be wrong about that)...

It seems you also have a Windows installation - do you want to be able
to dual-boot? Otherwise I think you can find the info you need in the
uefi(8) man page. AFAIR it pretty much amounts to "somehow"
mount_msdosfs-mounting the EFI partition and copying /boot/boot1.efi
from the FreeBSD installation to /EFI/BOOT/BOOTX64.EFI
(case-independent I believe, I actually have /EFI/Boot/bootx64.efi).
Should be doable from either of the <Shell> or <Live CD> (if present)
choices in the installer.
