Personally I always much rather recommend tutorials and books over video content.
Writing a tutorial or a book requires content-wise usually more effort, since you have to consciously think about the wording and allows you to review and edit, while for videos someone may make a second take, but there's a lot of low quality content on YouTube. Meaning the video is rather unstructured, just talking about stuff as they go, having limited knowledge on the content themselves while trying to "teach" it to someone else, and finally often containing lots of bad advice, especially when it comes to C++ code.
In my opinion the official tutorials are a must-read, even if you choose to watch some videos after all.
The tutorials cover all the important features and highlight common mistakes and things to look out for.

Personally, if you're interested, I recommend picking up SFML Game Development, even if some of the C++ advice is a bit dated.
I haven't really watch all that many SFML series of which a bunch exist on YouTube, so I can't provide any recommendation. A more C++ focused series using SFML to create an Arkanoid clone by Vittorio can be found here:
