One thing to watch out for road bikes is that they have very narrow handlebars. Appareantly at a 49cm shoulder span (bone to bone, not deltoid to deltoid), I am considered some kind of freak as far as cyclists go
I dunno your shoulder width but most people feel a little cooped up if they're on a handle bar narrower than their shoulders, I certainly did on 44cm drops.
Also, hybrids are still great for some light mountainbiking, fire roads and all of that. They're also good candidatesw for tourers. You can always just lower your flat bars if you want to get more aero, and there's a few handle bar options out there if you want more hand positions.
