By coincidence I looked at various embeds and tracking a few weeks ago ( https://www.zylstra.org/blog/2020/01/i-dont-track-you-here-but-others-might/ ). One of the things I learned is that YT videos have a ‘no cookies’ setting in their embed code. If you select share/embed there is a ‘privacy mode’ checkbox. It does not fully disable tracking, but tracks only visitors when the video is played. Then it is similar to that visitor going to YT. (It also means: don’t use autoplay)
