Where can I find learning materials with great UX?

Question

User interface

I believe that the best way to learn is the interaction of practice and theory. Theory should build on experience gained in practice, complement it and lead to more conscious practice.
Can you suggest examples of documentation or books that teach some subject, built on this principle, which can be a good example.
I refer to these examples as:

• "The Look of a Book" by Jan Tschichold. It is better to see and feel the modular layout once than to listen to long explanations.
  
• https://clojuredocs.org  is an example of good documentation, where many features of the language are confirmed by good examples, I wish other documentation would be like that.
  
• www.goodui.org — Mockups, supplemented with statistical data, perfectly complement each other and give an idea of ​​how to measure effectiveness.
