Instead I get all the files "firmware-sof-signed", but this package is not officialy installed
You selected the graphical installer which uses /install.amd/gtk/initrd.gz which contains these firmware files because they may be needed for sound and this initrd is also used by installation with speech synthesis. hw-detect.post-base-installer.d/50install-firmware copied these loose firmware files to the installed system as it does with any loose firmware files. It would not happen with the text installer which uses /install.amd/initrd.gz wich does not contain these files.
