A guide to writing English informed by recent scholarship (linguistics, cognative science, and such like).
"On Writing" is another book like "The Elements of Style", both are too prescriptive, albeit not useless.
(as a sidenote, trying to make a point about grammar made me very self-conscious about mine, this is why I had to read a good book!)
I used to use em dashes before they were cool. I actually learned about them when I emailed a guy who's a software engineer at Genius and also writes for The New Yorker and The Atlantic.
I asked him for tips on how to write well and he recommended that I read Steven Pinker's "The Sense of Style", which uses em dashes exhaustively, and explains when and why one should use them.
It also pains me that I can't use them anymore or else people will think an AI did the writing.

I also recommend "The Sense of Style"--knowing how to wield punctuation and grammatical structure is critical for clearly and successfully articulating your ideas--and I use semicolons, colons, and parentheticals heavily (but en dashes and em dashes are great too).
I find that dashes are great for conversational style flowing sentence structure, but sometimes they can become too long and tiring to the reader.
Also, read anything by Robert Graves. He did write a style guide called "The Reader Over Your Shoulder", but that's optional; I learned far more about good writing from "I, Claudius" and "Good-Bye to All That".
I also recommend the left-to-right, "topic position -> stress position" approach described in https://www.americanscientist.org/blog/the-long-view/the-sci.... I care more about whether I am making the reader do unnecessary work than whether I am entertaining to read or whether my commas are spliced.
