How can a I become skilled with popular front end frameworks quickly?

I'm a skilled data/backend/infra engineer who has been writing Python for ~8 years. I've written maybe a dozen lines of JS in my life. I'd like to be able to build a product with a FE component end-to-end on my own. Diving into the React or Vue ecosystems seems incredibly daunting to me. How would you get started on the road to mastering React or Vue? Online classes, tutorials, books, articles, etc.? Open to all sorts for recommendations.

I'm not looking for answers along the lines of "don't use React or Vue, it's too bloated." I'm aware of the what the ecosystem is like and that there are simpler alternatives, but for my purposes, I'd like to learn React or Vue.
