Would you get the same result with an unmodified ISO and that EFI
command line ?
(I.e. did the chnage from MBR to GPT do anything good ?)

Let's see:
wget https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/buster_di_alpha2/amd64/iso-dvd/firmware-buster-DI-alpha2-amd64-DVD-1.iso
The message can be found in the initrds for text and graphical install
/install.amd/initrd.gz
/install.amd/gtk/initrd.gz
I get from var/lib/dpkg/info/cdrom-detect.templates :
Template: cdrom-detect/wrong-cd)
to var/lib/dpkg/info/cdrom-detect.postinst :
devices="$(list-devices cd; list-devices maybe-usb-floppy)"
to bin/list-devices :
for x in /sys/block/*; do
...
syspaths="${syspaths:+$syspaths }$x"
...
if ! $match && [ "$TYPE" = cd ]; then
if device_info env "$devpath" | grep -q '^ID_CDROM='; then
match=:
The function device_info is implemented alternatively
if type udevadm >/dev/null 2>&1; then
device_info () {
udevadm info -q "$1" -p "$2" 2>/dev/null
}
elif type udevinfo >/dev/null 2>&1; then
device_info () {
udevinfo -q "$1" -p "$2" 2>/dev/null
}
The initrd contains a file
bin/udevadm
but no "udevinfo".
At least on my elderly system and with USB stick /dev/sdd it does not
report any line "ID_CDROM=" with
bin/udevadm info -q env -p /sys/block/sdd
It does report quite significant things like
ID_FS_BOOT_SYSTEM_ID=EL\x20TORITO\x20SPECIFICATION
ID_FS_LABEL=Debian_buster-DI-a2_amd64_1
...
ID_FS_TYPE=iso9660
I do get
ID_CDROM=1
from a Blu-ray drive at /dev/sr4.
But if i compare cdrom-detect.postinst and list-devices with those in the
initrd of debian-9.3.0-amd64-netinst.iso then i cannot find any difference.
"netinst" is known to work from USB stick.
So either i misunderstand the scripts or script execution should not get
there under normal circumstances.

You may try. But if this brings success, then the EFI firmware is really
odd.
It may well be that EFI's inability to offer the bootable partition
is independent of the debian-installer's inability to find the USB stick
as pseudo-CDROM.
Have a nice day :)
