OK, here are my thoughts.
1. The easiest path to becoming an NM strength player is to find one opening as black against e4, d4, c4, Nf3, etc -- and learn it well. That way, I will be theoretically prepared against players of equal or higher rating. In my opinion, it is difficult to achieve this level of understanding in multiple openings, and might I say not the best way to spend your time. It is much more important to study endgames than openings, and middlegame strategy and tactics. I just don't consider it that important, to be a theoretician in more openings than necessary.
2. The French is a counterattacking opening, kind of like the Sicilian in a sense, but doesn't give black as much a share of the center (from my admittedly poor viewpoint). But the reason I chose the Caro-Kann, long ago, was that when you play the French against lower rated players, you probably have to play 50% exchange variations. Not my idea of fun.
3. If you play e4 e5, you've got to instantly be familiar with all sorts of tricky white openings (King's gambit, Two Knight's/Giuoco, Ponziani, Four Knights, etc.) -- in addition to knowing a little thing or two about the Ruy Lopez. Granted -- I may know more about many of those openings than some 1300 player on chess.com, but I want to find something that suits my type of position, where I don't give too much up to the 1800s and 1900s, out of the opening.
you can't go wrong with 1...e5
