Have you tried PrepL library? You can filter out -don´t know if you are premium or not, since you need to be for seeing the cases-.
Furthermore, as I always advise all my coachees: don´t obsess too much about the industry. Once you know some overall basic data points -that are in most cases general culture-, it should not be an advantage to crack the case. It´s better to focus on types of cases rather than industries.
Hope it helps!
