Honestly there isn't anything that you couldn't get by simply reading and applying the advice from "The Elements of Style" by Strunk and White[1] and "On Writing Well" by Zinsser [2].
The primary philosophy is that if you can't write well, then you haven't thought it through. The act of writing is an act of reasoning.
0. Practice in a strong feedback loop. This applies for anything, not just writing.
1. Ruthlessly reduce your sentences. Repeat until you can't eliminate or combine any more words.
2. Avoid adverbs. Use "dashed" or "sprinted" instead of "ran quickly". Learn more words.
3. Avoid weasel words like "should" "could" "might". Take a stance and give concrete reasons.
4. Use concrete data over descriptors. "+5% profit" over "increased profit".
5. Write in active voice. Look up the "by Zombies" trick.
6. Use the simplest word that maintains your meaning. No one needs to use the word "utilize".

These style guides, especially points #1 through #6, came about from bureaucrats who were essentially filibustering or otherwise obfuscating in their writing.
The root problem there was not the long-winded writing, it was their intent to hide bad things.
If you can make sure you're not carrying water for corrupt officials, you best strategy is to try to write natural prose. Yes, do look for wordy phrases or cliches, but don't obsess over adverbs or the passive voice.
