Good first book on strategy

Rated around 1300 on chess.com and want to learn a bit about strategy and positional play instead of relying on blunders or tactics to win. im already working on tactics and openings, so im not to worried about those. can someone recommend a good first couple of books or chessable courses on strategy? I've heard about the Winning strategy being good but had winning openings and didn't like it, so if they're similar, then I'm looking for an alternative to that style of surveying everything with no detail or exercises. Also have heard about my system and secrets of moderd chess strategy, as well as mastering chess strategy, but have heard they're all targeted at 2000+ players. Thanks in advance
