Full screen hides the buttons by definition! However, you just have to move the cursor to the of the screen AND KEEP IT THERE for about a second or so to make them reappear. Your video shows your cursor barely reaching the top and "running away from it", never staying long enough. So you probably just have "push against the top of the screen" just a tad longer.
(FWIW, you are losing big on usability, and possibly the health of your wrists, by your antipathy towards keyboard shortcuts... just sayin'). Escape is such a simple shortcut, anyway. (there is also command-control-F to enter/exit fullscreen, which you probably don't want to remember, but Escape... to escape is as simple as can be.
