I'm just getting started myself, but my advice would be to stay focused. If you want to fight, focus on one or a few weapon systems. If you want to get good at mining, don't get distracted fighting or training up fighting skills. Use your initial faster paced training time well!
*shrugs* It depends on what you want to do. PvP, PvE, Miner, tones of options.
Gallente is drones and guns so some PvP utility there. If you want to go all out PvE then Caldari are ok being as they're missile centric.
Minmatar would be the iffy one to train they're kind of into everything and Amarr is into lasers and Armor tanking.
Maybe try a bit of each and see what works best for you? There is no "right" race in EvE it's just some do a certain thing better than others because of their ship setups.
I will say this though, PvP = Guns. PvE = Missiles.
I like to say "Missiles for show, guns for a pro".
