Discussed prior on this very website, there's no singular tool for determining good writing structure. That determination comes from experience. You'll come to understand which tool is best for getting your point across to your adoring fans. Making that point clear is your responsibility, "rules" of writing be damned.

Strong, confident sentences are excellent vehicles for making a point. Long sentences can lose the point, meandering around. Shorter sentences provide less opportunity for misinterpreations and fuck-ups. This makes reading and processing the information less taxing.

There is no singular tool for good writing structure. You simply need to use the tool required to convey your idea. The idea is in your head. It needs to get out of your head. How you make that idea available to people who are not your own brain is a miracle you determine. That's what writing is. Sentences can end in prepositions. And sentences can start with "and."

If the sentence is strong and confident, the writing has done its job, and so have you. Short sentences with fewer words have less opportunity to waffle around the point. Writing shorter sentences helps you present clearer ideas. Readers can follow them. It won't be a struggle to read.
