The best advice is probably to learn as much as you can from different sources but also keep a pragmatic point of view that helps to select the things that apply to your situation. Very often, new leaders follow a recipe without paying attention to the organization's problems. (check the book “The First 90 Days” by Watkins; it may give you ideas to organize your initial approach).
As someone who went from engineering to product design, I observe that CTOs without a product vision are challenging to work with. For example, at a previous company, a CTO tried to implement the hard rule that every UI component should be in the shared UI library. But, even when I was leading the design system, that rule didn’t match how a product design process works. It caused delivery slowdowns and a degradation of the UX. I can bring up other examples, and the typical pattern is a leader looking at only one aspect or two without balance. Try to go beyond engineering and learn more about business and product design, which will help you prioritize engineering decisions. Some product-related books: Inspired by Cagan and Well-Designed by Kolko.
Beyond engineering and product, as a C-level executive or director, people and hiring will be your primary concern. There are many management books, and I don’t have any particular to recommend (all of them will provide tools, but none is perfect: The Advantage and The Five Dysfunctions of a Team by Lencioni, The Phoenix Project by Gene Kim). I also enjoy taking ideas from biographical stories like Creativity Inc. by Ed Camull or Creative Selection by Ken Kocienda.
Finally, a book I found funny and cynical but depicts big corps very well is “Management Stripped Bare” by Jo Owen.
