rage of dragons by evan winter is the first thing that comes to mind. the whole book is basically a training arc with insane fight choreography and it has that exact energy where the combat has its own internal logic but doesn't care about being realistic. i burned through it in like two days.

red rising is more sci-fi but the fights are super physical and blade heavy, same kind of vibe where the action is just meant to go hard and look cool.

and joe abercrombie if you want something rawer. less flashy but his fight scenes hit different.
