I suspect that the Pro version will do a whole lot more than elements, I've never used the Pro version but have used Elements since Premier Elements 9 came out, I have 2018 now and it does all I need although I don't think it has the stereo spectrum capabilities mentioned, it will however separate the audio and video and can do a lot of the other audio stuff mentioned. I do think that a great number of serious YouTube vloggers do use the pro version because it does render faster if you have a nice gpu on your system. The newer versions of Elements will do 4K but you need a lot of processing power to do it, I think the Pro version is better at that but there is that subscription fee that may or may not matter to you.

You can do about everything on that list with Premier Elements with the main difference being Elements has no GPU support which can result in extremely long rendering times but Elements is not a subscription like Pro is and if you have the time it's great.

Same Setup as the sunflower.
