Hello! The fencing believe it or not will help, you likely learned a whole bag of things, from posture, footwork, timing, etc that you may see pop up during your training, just take any new classes as a fresh start and don't try to draw too many inferences between styles until you start to gain some experience. If you are just getting into martial arts and don't know where to start, your local MMA, BJJ or Boxing gym is a great place because the skills you learn in boxing, grappling or MMA style martial arts will serve you well no matter where you go or end up. Which style you settle on may have a lot to do with what is locally available so I suggest shopping around your town and seeing what's out there, likely one or more gyms will kind of call out to you as a better fit, considering the time and energy you will invest, theres no harm waiting for that one that "just feels right".
