Are you willing to pay for the text/audio? It’s unlikely that there are free alternatives that are also legal, unless you’re after literature in the public domain with fan recordings or something like that.

ltrs.me and ting56.com are much better, so many audiobooks.

I recently discovered https://www.ximalaya.com/youshengshu/. Seems like a good place to listen to audiobooks. Most of the ones I had a listen there sounded nice. By the way, I found it while looking through some books at shushengbar.net, they mostly post about web novels translated into English, along with the links to audiobooks and the original text, so might be of use to some.

Yes there are now a bunch of children’s books AND a series of books of simplified chapters from journey to the west that are available. They are in pinyin and simplified Chinese with English translation and a downloadable audio track. I recommend them! https://www.imagin8press.com/

I think audio books, at least if we’re talking novels, will not be extremely helpful. They contain an awful lot of vocabulary that are mostly found mostly in novels, so if you have lots of vocabulary yet to learn from dramas, there will probably me a lot more in any novel, including formal/written/literary language. I think the difference between the written and spoken language in Chinese is much bigger when it comes to vocabulary than it is in English. I’m not saying you shouldn’t try, just that it probably won’t be easy. 🙂

Instead, I would suggest that you read with digital support. That makes looking things up a lot easier and you can spend more time actually reading. Read more here. As for particular book recommendations, I think that’s really hard. I probably don’t like the books you do. 🙂 You could always check this post where I write about some books I’ve read.
