What should my first drink be?

So, I’m going to be 21 in a few weeks. I really don’t plan on doing anything crazy by any means, but I am curious what drink I should try. I really don’t plan on going crazy or anything, especially since I’m the first of my friends to turn 21. I’ve never really had a drink before, and I doubt this will be helpful, but I LOVE the non-alcoholic sparking cider. Any suggestions? Also, any suggestions on what to do on the actual day? My birthday is on a Friday, and I potentially will have a job by then, but otherwise, I don’t really have any plans.
