FWIW: option double click sny corner to make any window full-screen without going into full screen mode.

Double click any side or corner to move it to the edge of the screen, and hold down option to make the effect symmetric.

Nice - I didn't know about that one!

I just found out today that hovering over the green traffic light icon shows an arrange menu... but the "maximize" option there leaves some padding on all sides of the window - weird.

I swear by https://rectangleapp.com/ - same outcome but with keyboard shortcuts instead of the mouse.

Ah yes, the classic Apple move of hiding basic functionality behind obscure shortcuts. Thanks for the tip.
