Hide full screen button on all Mac OS windows? Is it possible, natively via Preferences or otherwise, to hide the green Full Screen button that appears next to the Minimise and Close actions on a window?

I always click it by accident and never use the feature, so would like to remove it if possible.
It is not possible to remove the green, full screen button from an app window's title bar.

To stop an app from going full-screen you can tap and hold the Option key, and the window will be maximized normally. (However, you won't remember to hold the Option key when hitting the button accidentally).
