I would sit down and make a list of the types of training you want to do, and a list of certifications and what their specialties are. You can then compare what you want to do with the certifications you’ll need. You also need to take a look at what the employers in your area are accepting if you plan to work for a gym/community center/private studio, etc.
I also agree that you want to get a certification that is NCCA accredited.
Good luck to you!
