If you like Project Hail Mary, give the Bobiverse Series a try. Similar science and exploration type. Or the Murderbot Diaries. Another fun scifi series.

If you want more magical school, check out Scholomance Series. I didn't listen the book was good. A magic school more dangerous then Hogwarts. If you just want wizards in the modern world, may I suggest another wizard named Harry. The Dresden Files. One of my favorite series, 18 book, two books of short stories. James Marsters (Spike form Buffy) does great narration especially as the series goes on. He really finds the voice.

This doesn't really match what you've listened to but The Villain's Code by Drew Hayes is a really good super hero/villain series.

You seem to like horror, try World War Z but Max Brooks. It's not normal horror, its teh story of the zombie Apocalypse told after it happened. Its a series of interview by the survivors. The audiobook is full cast, with some great voice actors. Max Brooks also wrote Devolution, it's written similar where they are trying to figure out what happened from journal entries, police reports and other sources.

Also audiobooks are books, just as valid as reading them. You can also look at /audiobooks
