Tastes are personal, so you'll never going to find consensus. You should read reviews to get ideas on types of frags that are around, what are their main characteristics, and the like. Then smell things yourself. Typically, it is wise to wait a bit before jumping into buying. Taste changes quite a bit at the beginning as you get exposed to more and more frags. Sometimes, by comparing different frags, you realize that the thing you liked at the beginning isn't as good as it could be, and there's stuff you prefer.
Once you've smelled enough stuff, you'll know what you like. So I would just go to a store (Sephora, Macys etc) and test a few (use paperstrips to bring back home as well). You cannot really test more than 4-5 per time, your nose gets tired. Go a few times, and by then end you'll probably have good ideas on what you like.
