I won't change your mind, but would agree with
@SILTHW . It's more about what camera "ecosystem" you want to "marry". As you start to collect more lenses and batteries, it becomes harder and harder to switch platforms!
I went the Sony route with a Sony a6400. The Sony mirrorless cameras are one of the thinnest from sensor to lens mount and can therefor be adapted to most any other lens mount if desired. Also shares the same mount (Sony E Mount) between APS-C and Full Frame. So if you start with a crop sensor camera and later upgrade to full frame you can run their full frame cameras in a "crop mode" and keep using your lenses as a transition step. Canon has a bunch of different lens mount formats and I think just invented another new one.
That said the Canon M50 is a top YouTuber pick, right next to the Sony a6400. I think they are both top picks and comes down to personal preference (and maybe which YouTubers you like to learn from. Peter Lindgren = Sony, Tom Buck = Canon, Jason Vong = Sony, Potato Jet = both - but more Sony, Peter McKinnon = Cannon, DSLR Video Shooter = Both). So you may just like tutorials from certain creators you are subscribed to and that will influence your personal preferences.
