I've seen zero length grub.cfg before, but it was on XFS, and it was
because of an unclean umount, and GRUB doesn't support journal replay,
so it could only read stale file system metadata. After coaxing normal
boot, kernel XFS code did journal replay and the grub.cfg was no
longer zero length.

That isn't what's going on here, FAT doesn't have a journal. It might
not be a bad idea to unmount /boot/efi and do an fsck on the ESP using
-av flags. On mount, the vfat driver sets the dirty bit on the file
system; and /etc/fstab as created by anaconda calls for running fsck
if the dirty bit is present. So...I doubt the fsck will find anything
that it can fix, but ... wheee!
