When trying to Google for something, I found that the search term "layout and composition" seemed to give a lot of "decent" hits. Other search terms seemed to give a lot of "false positives".
I did not spent time to check all the individual hits thuogh.
In think web pages or books are better than videos, becuase they give hands on examples.
I once found a text that was typset in like 15 different fonts, just for comparison. And the fonts were not completely different styles, but rather very similar.
I tried to look at my old printed documents for hints to where I found them, but most are in Swedish.
