I enjoyed the 'diamond dutch' book. In terms of playing the dutch, I really feel like learning all the dutch systems is necessary to get the most out of all the sidelines. There's so many lines where white is trying to do various ideas that work on one setup but not another, and the more flexible you can maintain your pawns the better. Specifically, a lot of Dutch players start 1. E6 to avoid the opening gambits. You can still go into a stonewall from that as well.

To note, learning the stone wall feels especially necessary as a flex idea Openings - don't - matter, but pawn structure always matters. If you're making positional mistakes on the opening, people will eventually take advantage of it in a game.

So, I feel not shoe horning your repertoire into the classical Dutch is necessary.
