The manual in the "Official Raspberry Pi 5 Desktop Kit - 4GB (DE)" is in German. The name "(DE)" in the product title indicates that the kit is intended for the German market and therefore contains German documentation.
I bought the DE; the book is obviously in German, and the keyboard is German QWERTZ. I don't know about FR, but it's probably AZERTY. Of course, I would have preferred French-speaking Switzerland. In the absence of this possibility, the German QWERTZ is quite similar.
