Welcome!
If this is you first ride street or dirt, I would go with something not intimidating and up right with your legs under you. Every bike IP mentioned is a good choice and will not overwhelm you while learning the ropes.
Would advise against going with a full cruiser with forward controls. Having your legs and feet out in front of you makes learning harder and you will not be able to learn proper body position.
Have a 2007 Kawasaki Ninja 250 for sale if you are interested (a friends bike that I prepped for spring, but he does not want it to come home). Have not advertised, but it's like new with 3400 miles and new tires.
Good luck with the process, it will be fun!
