I studied Aikido for about three years and really enjoyed it for it's pacifistic and abstract spiritual philosophy. It's non-combative in nature and usually includes a written component when it comes to gradings.
Training in it also helped me make key lifestyle changes and became a kind of physical therapy from the depressive rut I was in at the time.
As for what type of art to go for, I guess it depends on what you're really looking at achieving with it. There's lots of options out there.
