Sounds like you’d be into Truffaut’s book/interview with Hitchcock (https://www.amazon.com/Hitchcock-Revised-Francois-Truffaut/dp/0671604295/). That will probably inspire you to see Hitchcock’s collective work.
A subscription to criterion would probably do you well too.
Check out the critical studies film program at USC.
I would recommend almost everything in this thread, but I'd like to suggest <em>Hitchcock</em> by Francois Truffaut. It is one of the greatest interviews with one of the greatest filmmakers, any aspiring filmmaker MUST read this.
Hitchcock Truffaut
Really the best book about the process of making film. Two masters of the craft dissecting each of Hitchcock's works. Great read.
This is a little less immediately practical, but Hitchcock by Truffaut is one of the best books I've read on directing. Any YouTube video can teach you how to read a light meter, but this book is a conversation on the art of directing by two of the most thoughtful directors at the time:

Easy Riders and Raging Bulls - Peter Biskind
Hitchcock-Truffaut is one of the best books on film theory you can find. An interview between two legendary directors.
My problem is that everyone is at a different level, so the right book for me is wrong for everyone else.
Given that caveat, I'd recommend Hitchcock/Truffaut. Truffaut was brilliant in his questions, and he seems to have understood Hitchcock as a director. And when Truffaut didn't understand something, he asked, and when he disagreed, he told Hitchcock, who treated the disagreement with respect.
I recommend the book because Hitchcock explains his thinking and his technique. While no one should copy another, having that insight to Hitchcock can be very valuable in directing, cinematography, blocking, and more.
I understand Truffaut filmed the interviews and released a movie, but I haven't seen it.
I learned quite a bit from the Guardian's eyewitness app It combines the best photojournalism with in depth captions to understand why the photo works.
A classic book of cinema is Truffaut on Hitchcock. Definitely recommend checking it out.
