If you are looking for an a level that is lighter in content a level media is definitely the way to go it is probably the easiest out of the a levels I do (Sociology and English Language) In terms of what is covered in media its everything in media you can imagine : Films,TV, Music, Print, Games, Newspapers, Adverts, Radio, YouTube and probably more that I can't think of. If you like essay writing that's what media mostly consists of along with some short form questions. You have questions about pre studied texts along with texts you've never seen before.
However, if you are considering Law (I don't think it matters as much with crime) like you said English a level may be a better option as I think it's highly respectedin the field. I only study English Language so I don't think I'd be able to advise you on what combined entails.
If you have any questions feel free to ask me!
