For windows, just use Dawn dish soap. That’s what professional window cleaners use. They’re not paying out the nose for special cleaner. They’re just squirting some Dawn into a bucket, filling it with hot water, and using that. It cuts grease like nothing else, so it doesn’t leave streaks when you squeegee it off.
Also, for things that are stuck, an old trick is to use steel wool. Glass is (or at least should be) harder than steel, so it shouldn’t scratch as long as you’re gentle. It’s nice for when things need to be scraped off.
For home and auto, yes this is a great way to clean windows. I use Zep’s simply because I have experience with it, and I only buy one can every two years, it’s a small expense but worth it to me.
I had to use Zep’s when cleaning aircraft windows since 1) that was what was provided to me, 2) commercial and corporate jet windows have to be perfectly clear during a flight since there’s no pulling over to squeegee the cockpit window if the cleaning crew messed up.
