Since time ago and after upgrading I realize that macOS began abusing of fullscreen feature, and personally I hate this behaviour.
Maximize icon goes to fullscreen (hides window header and dock)
Maximize icon, keeping pressed offer tile to left and tile to right, but not and option to fit to screen
Exit fullscreen (from Menu;View) moves to a small windows and does't fit the window to the screen
From system preferences I can't see any option about the fullscreen behaviour.
At the moment of writing I am on macOS Catalina.
