I suggest "The Writer's Journey," which uses Joseph Campbell's "Hero w/a Thousand Faces" as its jumping off point. However, it makes Campbell's tome, which I only made it through a few hundred pages of, more practical.
As well, a book with a terrible title, "Writing a Great Movie," by Jeff Kitchen, has been really indispensable to me. With its title, I do not want to be seen reading it in public, but it is immensely useful. Using 10 or so known films, it analyzes how the scripts employ various tools Mr. Kitchen talks about.
The tools are not all of the typical things you get in every other book. He has a genuinely novel approach to writing, in many respects. The book actually helped me to fix a piece I had written that went on to win some awards. Some of it, of course, can be found everywhere, though.
Also, I recommend reading screenplays. It's fun this time of year to go to The Golden Globes nominations and pick a few of the screenplays to read. (You can always find them online by googling, for example, "JOJO RABBIT FULL SCRIPT PDF"). (I don't actually know what is nominated for The Globes this years. So I reached back for JoJo...)
Those are my 4 cents...
