Sounds like a Hybrid (aka comfort bike) is your best bet at this point. I agree with those who said that there is little difference between models when you are buying an entry-level comfort bike and that the bike shop is way more important than the brand. Along those lines, go to a shop that's been there for a while and that uses a professional bike fitting system. Pay the extra hundred plus for a good fitting. It will make WAY more difference than disc brakes, lighter weight, more gears, etc. Bike fitting, both the science and art of it, has improved a lot over the last few decades. Everyone's body is unique and there's much more to bike fitting than seat height and making sure your knee is behind the pedal axel. The best bike in the world is the one you like to ride and you won't like any bike for long if it doesn't fit you well.
