It is my goal to balance everything out and make it an even playing ground :P For example long exposure tends to be more difficult, while smartphonephotography is more about the basics. Sports photography also seems to be difficult for people but in another way, it seems that most people do not have access to many sportive people in their surroundings

Yes, I understand how you do it @juliank :) It is true that on my side, between my studies in photography and my few trips abroad, I have made many pictures, many of which are related to the competitions you propose.
For sports photos, participants should not hesitate to visit the stadiums and sports halls (open to the public for free), there are often matches and training sessions.
