Blanchard has a really good Macroeconomocs book. I used the one called Macroeconomics: a European perspective. It is really good in the sense that it shows you from where everything is derived from, so you actually understand and learn rather than memorise formulas and theories.

A lot of the stuff you are reading are more philosophical/ historical so if that is what you are interested in then the works you've mentioned should be sufficient. However some of these texts I sometimes find a bit boring for my liking, so if that happens to you you can YouTube discussions on the topics.

I would elaborate on anything you don't understand using YouTube. There are so many videos that explain macro theories so well and put ideas in simple terms. Also, there are many macro lectures from universities that are posted online so I would also check those out.
