I practice aikido. As someone else here mentioned, it's a soft style in that it's less about striking than speed and timing. It also consists of mental training: quieting your mind and removing unnecessary thoughts and distraction (it's been described as "meditation in motion"). Some downsides: it takes a long time to get to any level of proficiency, it's non-competitive (so unlike fencing, there are no tournaments to compete in), and only really useful in defense. As with any martial art, the critical thing is to find a good teacher. The best advice might be to visit several dojos of the different forms people have mentioned here, and see which one suits you best.
