Reddit reviews The Age of Battles: The Quest for Decisive Warfare from Breitenfeld to Waterloo

The best book, far and away, is Russell Weigley's The Age of Battles. Weigley explores the evolution of modern military strategy from its roots in the 30 Years War to the defeat of Napoleon at Waterloo. He does exactly what your question asks, tells you how generals planned and fought battles from the 1630s to 1815, as well as telling you a bit about pretty much every major war and battle between. Plus, he also ties in the evolution of naval strategy, such that it was, into his narrative.

I cannot recommend this book enough, as it is exactly what I think youre looking for.
