Parksstp, I was kinda hoping someone would do a post like yours. I've spent countless hours trying to make the Stonewall work against a black Kingside fianchetto with no luck. I have won a few games like that but it was more that my opponent was weaker then me than the opening I played being sound. As my rating got higher more & more of my opponents played a Kingside fianchetto defense & the more I struggled with it. It totally blunts the Bishop sacrifice on h7 as well as the Knight outpost on e5 & without those the Stonewall is pretty much useless.
I gave up playing it for a while then I tried transposing to some form of Queens Gambit when I saw g7 being played, that was far more sucessful.
There was no internet back then so it wasn't easy to find literature on something so specialized, since I returned to Chess it's a different matter. I found this on Youtube, when not to play the Stonewall & how to use it against a fianchetto defense. I wish I'd had it years ago it would have saved me a lot of pain.

For anyone watching this thread who may want to take a further look at the Stonewall Attack there is a 4 part introduction to it on Youtube. It will get you started & show you how to play it & more importantly when not to play it.
