Answer 1

I found a solution that works for me. As in many cases the problem was sitting in front of the screen and simply doesn't work precisely enough ;-)

Instead of using

options.add_argument("--lang=de")

you have to use

options.add_argument("--lang=de-DE")

When I use an IETF language tag the code I initially posted works as expected.
