Hey, welcome!
I'm no expert, but a hybrid sounds like a good idea for you according to what you say you want to do right now. You are being smart by trying out different bikes in different bike shops. The more bikes you ride before you buy, the more you will know exactly what you need in a bike. Try to resist impulse buys unless you are like suddenly crazy in love with a particular bike. If you aren't quite sure,- keep test riding.
Good luck! Try to enjoy the search for a bike, meanwhile.
