Personally, I think cream of mushroom makes a great gravy for meat, particularly pork.
With what you have, I would mix the 2 mushroom soups and use the gravy mixes too.
But then again, I might change my mind, depending on your recipe, or what you consider "proper" smothered steak.
And welcome to the neighborhood! Pull up a spatula and help stir the conversation pot every now and then!
