Would second Ktrain's advice not to be tempted by the knobby tires or suspension. If you start wanting to explore off pathway then you get to buy a new bike, N+1 baby!
A comfortable hybrid will give you great range for your dollar. I don't think you need to rent to see what you're getting into. A good bike shop should have a bike close to your size and preferred style that you can take for a test ride around the neighbourhood (might be harder with current supply chain issues though).
