I would say just start with the React tutorial and use the react-create-app (uses webpack etc in the background and is a npm package) that they use in it. Then after the tutorial I would go into the docs and read through them and maybe test some.

After that I would pick the state management tool I want. Either Redux or Mobx as both are popular and have their advantages and disadvantages. I think it is worth going through both their official tutorials as they are pretty good.

There are of course tons of videos but I think the official tutorials are a great start and using react-create-app instead of trying to dig into webpack and all that is really good at the beginning.
