I’d recommend The first two sections of On Writing Well by William Zinsser - it’s short and following the guidelines will get you to clear understandable writing. If you forgot what is said, you can just read these short parts of the book again. The later sections can be referenced as needed. Writing is hard. You need to edit again and again to get clarity. Programmers are used to this in code, but text is no different.
