Hit Enter too soon on my previous comment. The "dpkg-reconfigure grub- efi-amd64-signed" reproduced the issue, and again, had to grub-install via a hirsute USB install disk. (Same command as previously reported, although I dropped --uefi-secure-boot this time around out of curiosity, and it still worked.)
