The true answer, which may not be useful, is that style is what happens when one writes five million words. For the first few hundred thousand you end up sounding a lot like your favorite authors and what your teachers wanted. Then you start doubling down on what is working, try random experiments, bounce around an incentive gradient a bit, and also accumulate a decade plus of life experience and hopefully some knowledge. Eventually, people start sounding like you. There is no day in the middle where you hire a focus group of writing professionals to develop a house style guide.

That is a joke but not much of one; writing style guides to capture "What is... taste? How do we scale it?" is a project I've actually been involved with. This project brief has defeated many talented people, the least of which being me.
