It’s very rare that I maximize an application. I’m always stacking. However, I don’t think it’s an optimizing assumption: I am frequently fighting with the window manager as I rearrange my windows and it automatically maximizes them because I got too close to an edge of the screen

In general my browser is dead center or slightly to the right so I can access my other windows (terminal, throw away text editor, etc) easily where command tab is insufficient (when I have multiple terminal windows, eg)

Turn off System Settings -> Desktop & Dock -> Windows -> "Drag windows to menu bar to fill screen"
