Recommendations for preparing N1 Reading and Listening parts

Hey there.

I'm motivating myself to take N1 in December (passed N2 some years ago), but I'd like to ask if anyone has recommendations for what to read and listen to, to do good practice for the test. I'm already crunching a bit regarding grammar and vocabulary, so I really want to invest my time efficiently.

I know the JLPT (especially N2 and N1) features more formal/stoic Japanese than some content present in the entertainment medium (like anime or games). I'd prolly have to stick to the news or some serious podcasts, but I'd like to read and listen to something I'd enjoy, if possible.

I have some light novels that I bought some months ago, but I'm a bit afraid they won't be of much help because they're fantasy novels (Tensura, Kusuriya and Kagejitsu).

I'd like to know your recommendations!
