These are all tutorial-level documentation. Once you've gone through those you can complement them with the MDN documentation on the individual properties as a reference.
I can't recommend the css tricks guide enough. I don't write enough css to know the properties by heart but with this resource it is easy to find quickly the property you need.
Yeah, I have both of those bookmarked myself. I know they sell posters of the articles. I've always wanted to get them, though they're a tad pricey. But I guess I can write it off as a business expense…
Ah I came here to recommend Flexbox Froggy and Grid Garden! I didn't come across them until long after I needed them, which is really a tragedy, but I try to rectify it by linking them to everyone I come across who is learning css (which is a lot of people due to some Discords I'm in). They're adorable and wonderful, and if you don't use css frequently enough to keep the properties memorized, but do use it enough that it would be convenient to be slightly more familiar than needing to re-google constantly I recommend re-playing them once a year or so; they're honestly pretty fun just because they're so cute.
For CSS Grid, the equivalent resources would be https://css-tricks.com/snippets/css/complete-guide-grid/ and https://cssgridgarden.com/
