Have a sympathy upvote for your wok hei. I love my cast iron. And my enameled cast iron. And my carbon steel. And my copper. I love my Japanese santoku and my German steel. Different tools for different jobs my friend.
That said, if you had to populate a kitchen, from scratch, on a budget, cast iron as your main skillet is a good idea.
