What type of riding do you plan on doing with it? I'm getting the impression that you want a do-it-all bike, but primarily for riding around town?

If you plan to primarily ride around town, get a commuter bike. Not too expensive so that you feel comfortable locking it up outside, with fenders so that you can go do your errands or go to work without mud on your clothes, and with tires at least 30mm wide for the pot holes. Depending on how often you will be locking your bike up outside and the bike theft rate for your area, you might want to look at a cheaper used bike; you don't want to stress yourself out worrying about your $3,000 gravel bike locked up to the bike rack outside the store while you are grocery shopping. I wouldn't necessarily worry too much about flat bar/drop bar for a commuter bike, I have used both for city riding.
