For black, I would recommend the Queen's Gambit accepted against d4 and the Scandinavian Defense against e4. Sure, it may only be one pawn, but you'll immediately notice how much your position opens up with just that trade. For white, you can play e4, and openings you might like may include the Ruy Lopez exchange, which is drawish from the outset. However, when many people say they are trying to play for a draw, they lack aggression and make defensive mistakes, which can make it quite easy to lose in the end. One one hand, you will learn something with whatever opening repertoire you happen to choose. On the other hand, this most likely isn't going to be where you'll spend the rest of your chess career.
