You can two-finger drag to make the selected app move around, although I rarely do so.

You can also three-finger drag down on the selected app to get Mission Control view for that app, to select a window directly. I do that somewhat more often.

Those are the other ones I know. Discoverability of the various affordances in the macOS interface is terrible, but it stays pretty consistent over the years.

There should be a manual of a couple hundred pages. I miss the days when that was standard.
