personally i would steer clear of akitas but like i said, thats a personal opinion. all the qualities you're looking for in a dog, you, for me, just described a GSD. They're an amazing breed and i cant ever imagine my life without at least one. GSDs are an addiction. Proper training and socialization, you can have the best dog in your world. I wouldnt trade my dogs for anything. i honestly think the best way to know for sure if a GSD is for you, is to meet various dogs, learn about the different lines, talk with owners. They really are great dogs and could fulfill everything you're looking for.
