SV 650 is a good bike to look at for a first bike. Light and flickable, easy to learn to ride and some room to grow into. I’d say its more about your physical size and what you want in a bike.
As to equipment, Helmet (full not just a brain bucket), leather jacket with shoulder and elbow armor, gloves jeans and ankle covering shoes. Shoes should also be leather and steel toe is good too. Most of these items can be bought on CL for a lot less than new, usually less than half.
