I would like to recommend the recent book “Fundamentals of Software Architecture” https://www.oreilly.com/library/view/fundamentals-of-softwar...

It covers important foundations, walks through different architecture patterns. The last part of the book is about soft skills: communications, decision making, etc. In my experience, it is critical for such position. The book is different from piles of enterprise architecture books that talks a lot about UMLs, formal processes, ceremonies, and roles - things I found either irrelevant for my jobs or I can learn them better elsewhere.
