An another type of learning tools are courses on Chessable. Several of these have a video, which often is expensive, but gives more info then the plain text versions.

I bought a course of IM Andres Toth (Chess Principles Reloaded - Center). I think he is one of the best teachers on the net. 

But afterwards I have been thinking what I did learn from this course, if anything. The centre is important, but I did know before. 

In there course there many example games from GM games with tests. But I feel these examples are on a level high above me, even if I understand the explanations. 

If you compare the amount of the content of a chessable course and a book, probably the book has lot more of content, and maybe also a better for learning. (If you read and work through the book, of course!). But for some maybe it's more interesting/fun to do a chessable course, then reading a book.

Do what strong players do. Or, do what strong players did when they were at your level. Strong players make videos, but to my knowledge they don't watch them much, nor did they at any time in their development.

To my mind the worst part of videos is they allow the viewer to fool themselves. The type of things you can learn don't really help that much in a practical game. It's like the difference between understanding the concept of relativity, and understanding the mathematics of it. With the concept, you can sound smart in a dinner conversation. With the mathematics, you can solve hard physics problems (but you can't explain it later at dinner).

On the other hand, a video you will watch is better than a book you won't read.
