I’m embarrassed to say that I’ve been using Mac for years and still don’t know how to make an application fullscreen like Windows does. The green button hides the menu bar, and alt clicking the green buttom makes the app bigger but doesn’t fill the whole screen.

Either I am stupid or Mac is bad at discoverability.

You can set it to not hide the menu bar in fullscren mode. By default it will show up when you move the mouse near the top of the screen.

rectangleapp.com enables the classic fullscreen with ctrl+opt+enter (or via snap to top).

Option + double click on the corner of the window (where your mouse changes to the diagonal resize arrow).

I switched from Win10 to macOS recently and had to search the web to find this, so discoverability is certainly an issue. I suppose Apple would rather you just fullscreen a window than maximise a la Windows.

To make it maximise the area in your current mac Space (i.e. not go "full screen" in a new Space) you can go: Mac Menu -> Window -> Zoom. I just usually double click the App's window bar and it stretches the same way.
