I have a few workflow solutions to this, but Control Down-Arrow or three finger swipe down is the most common. Also, windows are in a stack from least to most recently put in front, so if I know something is toward the back I start with command-~. I also happen to believe that there is such a thing as having too many browser windows open, so when these strategies start to become unmanageable, I will close some. The Expose for browser windows takes up to twelve before it needs to make the icons really small, that's a reasonable limit for me, especially given both tabs and tab groups (which I'm increasingly making good use of). To be clear, this is a workflow, not a workaround: unlike focus follows mouse being impossible, I'm content and productive handling the browser this way.
