It's a very good bike for a beginner. In fact you might never 'grow out of it'.
It's very important, especially for beginners, to be able to sit on a bike with both feet flat on the ground. The first poster here thinks it will fit you, but you can't really be sure until you actually try to sit on one. For short people ('inseam challenged' we call them) this can limit the choice of bikes. Cruisers are the 'shortest', and have the added advantage of being easier to manage because their weight is lower. But I'm not a cruiser person myself, so if it was me I'd at least try the GS first.
Good luck!
