Just remember back "in the day" that a bike called "hybrid" can mean in its basic form, was a bike that you sit upright on and has a comfortable ride and easy gearing. Now there's a lot of bikes that fit that definition but aren't necessarily "hybrids" or might be called a hybrid but are just road bikes with flat bars.
If you're looking to ride upright, look at all bikes with flat or raised handle bars and ride them to see how they feel. Some people like a bike that is heavy and handles slowly with a spongy soft suspension. There's some that want a lighter, fast handling bike with a slightly stiffer suspension. They both can fall into the "hybrid" category, it's up to you to decide what you like. Just don't focus strictly on a bike that's called a hybrid, look at "fitness", "cross trail" and others that look to fit your need.
Once you figure out what you basically want, then it just comes down to how much you want to spend. To me that's where it really gets fun when looking at a new bike.
