Does a Golden Retriever sound right for me?

I want a big dog. I know that - I've never had a big dog before and I just love the way they are. Also, I want a really playful dog that I could play fetch with. I have an average sized yard but will give a good amount of exercise. Also, this will be my first dog I am fully responsible for so I want an easy to train dog that has low dominancy. I know about the grooming, it doesn't seem too bad and shedding isn't really a problem for me. So, does a Golden sound right for me?
