There's a demo on Steam if you want to try it out. If you're struggling with move inputs, the modern control scheme helps a lot with easing you in on the game. And, apparently, the single player mode World Tour is really well-made while teaching you some fundamental concepts effectively (I haven't tried it yet, that's what I read).

Unfortunately, I don't really have a video or a review that describes the game in a newcomer-friendly yet succinct way. You can always search for rooflemonger's street fighter 6 videos. He has a 30 minutes long review of the game if you can stomach it. He also has an hour-long beginner's guide and a 2 hours-long(!!) character guide if you really want to get into it or if you just found a character you vibe with and want to know more about them.
