Ask HN: Recommendations for clear and concise writing classes/resources?

Long time reader, first time posting.

I am a manager and lots of my work requires me to write about ideas, projects descriptions, designs, and status updates in a clear and concise manner. My writing skills are intermediate at best and looking to improve them in terms of clarity and length. So far, I’ve identified two books: “On Writing Well” by William Zinsser and “Style: Ten Lessons in Clarity and Grace” by Joseph Williams which I am planning to read. I prefer classes or courses where you can write something, and a person can give you a critique with an explanation and how the content is supposed to be restructured.

What are some recommendations for courses/classes (Bay Area or online) or other resources?
