I am also in a similar place. The things I have seen work for me. First, sign up for a Grammarly premium account. It identifies easy fixes, and you do not even have to think about punctuations. And it identifies places where your words are redundant. You start noticing patterns. I tend to use "really" a lot. So being aware of that helps me change my writing style. Grammarly also points out better words to use, but I have found it works only 10-20% of the time. That is still better than nothing. Then try cutting down your text by 50% and then again by 50%. I found my text to be wordy, but cutting it down helps clarify the text. And editing is more important than writing. I always find it easy to write the first draft then spend hours editing, which I never used to do before. And then read a ton, especially fiction books. They seem to use exciting(Grammarly changed "interesting" to exciting here) words. Keep notes of what has an impact. And then you can use it in your text. I hope that helps.
