I guess you are native German. Just in case because learning German would be something extra.
IFR will be done in English anyway (I hope) and VFR has so little communication that I do not think that matters. Of course it will depend where are you flying but I do not expect you to learn to fly somewhere in CTR anyway. It has no use.
I see bigger differences in aircraft. I was lucky to fly old machines where instruments were like "this thing is not working" or "there used to be something" then we have classical instruments but working fine and then there were glasscockpits and it was "Look at that. It is so easy. It can do so many things." It was great experience. You could realise how intruments work (or not) how they can help. Glasscockpit is a thing these days but it would be a pitty to miss old school. It is really hard. I just wanted to show you the meaning of that.
In case you would pick glasscockpit is there a chance to try classic thing for at least few hours?
