Tarot Guru itself has one that I used.
I think a lot of people tend to get something that helps them start, but then we all kind of find our own way after a while. Rather than going out and buying a course, I would start by reading this and this.
Podcasts could work well for how you learn. I listen to them while doing other stuff - walking, cooking, whatever. Way easier than sitting through videos. I keep a notebook around to write down card meanings when they come up. Sometimes I’ll sketch the cards too, which helps me remember them better. I like to just keep a little drip of constant information and learning rather than trying to cram it all in at once.
