I've seen a bunch of satellites when observing, especially with binoculars where you get a wider view. Usually, they shoot past and are little more than a tiny spot (looks like a fast moving star).

I've seen Iridium flares back when they were a thing.

I've seen the ISS several times including with a scope at relatively low power once where I was able to see structure and even color. That was very exciting.
