Launching the kernel stub binary directly in qemu (v8.2.4) using the command in my original message, the stub seems to attempt to print something to the EFI console, but it ends up showing as many characters of whitespace and simply quitting after 5s. I guess this shows the bg_gen_unified_kernel script is OK and the issue falls in the stub? For the record, the efibootguard binary itself seems to work just fine. Thanks Chris
