Same. My eyesight getting worse has been a big factor for me. The days of having all my active tools neatly organized and visible simultaneously is over, even with multiple large monitors.
Why not just have all your windows fullscreen and three finger swipe between them like macOS was designed to be used. If you dont like the extremely opinionated macOS window design why not just use Linux?
So I've embraced overlapping windows. I strategically place them so that the import parts are visible. For example, my IDE is full screen, but the browser is only 70% with and height or so (so that the left 30% and the bottom 30% of the IDE are visible, which conveniently lets me peek into the log of the currently running program.
I have a Hammerspoon configuration that conjures up a modal window on a keypress, and then additional keypresses move the current window to a predefined position and size, e.g. m to maximize and p for the top right corner (70% width and 70% height).
I also have some keybindings in that modal window to jump to an app, e.g. w for the browser, i for the IDE, t for the email client, space for the terminal.
I very very rarely manually move a window around, one of the preset positions/sizes usually works for me.
