My personal solution is to play everything with mpv instead: From YouTube's SERP, I copy the link to the video and run `mpv "$(xsel -b)"`, which downloads the video with youtube-dl and plays it in mpv, i.e. in a desktop app. No bullshit, no autoplay, just plain video and audio. As a bonus, this works with almost any website containing video, so the player works the same regardless of website.
Yes! Added advantages that it skips ads, and has keyboard control for all sorts of things that are sometimes useful depending on what you're watching or listening to: playback speed, A-B loop repeat, adjust brightness / hue, pause, frame advance, take screenshot etc.
