The American Library Association posts "most challenged" lists, unfortunately not by state. Here is the top ten for 2024, and if you scroll all the way down, there's also links to the top 100 from each of the past 3 decades (if you want historical data). The ALA has an Office of Intellectual Freedom that absolutely collects all the challenged/banned book data, but I couldn't find it posted anywhere (closest is this, but more recent years are missing... can probably supplement with here).
