I am doing a similar thing for my epq, I think all these topics would be good in terms of having a lot of different opinions and point of views. However in my opinion i think the first option or sort of area/theme would be a good idea as there, from what i have researched, are a lot of differing ideas and almost controversy on the topic depending on the persons views or maybe even from where there from which I think could be interesting to research. Then again they all, in my opinion, would be good areas to focus on (i might be a bit too late but i hope it goes well)
