If you're not using a tiling window manager, maximizing windows that do their own tiling (e.g., tmux, Emacs, vim, iTerm, Konsole... whatever) is the only thing that makes sense. If you're visually impaired, you'll also likely find yourself needing to maximize because all of the blank space used in modern design trends means that if you scale up the app or the font sizes, all that empty space the app is burning up forces you to maximize the window just to fit the important elements on the screen.
