Your dominant foot is the foot that you most feel comfortable balancing on. if you make contact with a soccer ball kicking it with your right foot,the it typically will be the left foot ( or regular). if you wakeboard, long board it usually the same stance. I would stay with the goofy stance since that is what you are comfortable with already long boarding. Don't worry about all the other tests. You already participate in a sideways sport so stay with that. Some people are so close/even it really doesn't matter. It would be a good idea to ride switch a lot. It will make you versatile.
That's weird you mention that. I am right foot dominant when it comes to things like kicking and such, but I longboard/snowboard regular. I am tempted to say I have pretty decent form as well with minimal to no rear foot steering.
