If you ended up not checking "Remove requirement for an online Microsoft account" there are still ways of using this installer. To be prepared, download the Framework Windows 11 driver pack .exe file and drop it onto the bootable Windows installer USB you just created.
In the Windows installer, once you get stuck because Microsoft wants it to be online for you to sign into your account - this is still in the installer and there is no driver for the FW16's wifi adapter or the ethernet expansion card. You can make this work with a 3rd party USB wifi or ethernet adapter that Windows installer happens to have a driver for - or alternately install the driver pack right now. Here's how:
Press Shift-F10. That will bring up a cmd.exe window where you can launch the driver pack installer from the Windows install USB if you had put it there earlier. If you're not comfortable with cmd, then in the cmd window simply type explorer.exe and Windows explorer will come up to let you browse for the driver pack installer.
I bought a key to Windows 11 Pro and the first time I installed it, skipped entering the key in the early stage of the installer so I could enter it later. It then asks which version of Windows to install, as mentioned in this step. It's possible I didn't select the right one, or something else went wrong because after Windows was installed, I wasn't able to apply my key.
After starting the install over again, I entered the key from the beginning of the installer and it skipped asking for which edition, and Windows came up activated. Funny thing is, Windows claims to be Windows 11 Pro, exactly like what I had chosen the first time.
TL;DR : it might be beneficial to enter the product key at the earliest possible point in the installation.
