ok, lets go down on the amount of debug to start then:
make bin-x86_64-efi/snponly.efi DEBUG=snpnet,nii
(note using snponly.efi here not ipxe.efi, to minimize possible problem sources and only concentrate on the nii/snp issue)

Assume your menu was shown but got a lot of debug output that got the menu of screen, so maybe just put in a sleep 5 instead, hmm 5000 is milliseconds (my misstake earlier), so waiting 5 seconds fails, but waiting just 3 works? (could you please try your original ipxe with sleep instead of menu in the script?)

snponly.efi only has support for the nii/snp interface which is in the EFI spec i belive, you can see snponly as the efi equivalent of undionly.kpxe, while ipxe.efi have "all" the drivers that ipxe supports, including snp and nii to fallback on. For efi you will probably want ipxe.efi if size is not a limiting factor, the only other case where snponly.efi might be preferred instead of ipxe.efi is if ipxe.efi is causing hangs during boot, but in those cases please report since it clearly is a bug that we would like to get fixed.
