I’m not seeking background reading on these concepts as they are already bundled into their own taxonomy, that’s the thing I find unhelpful and am seeking to avoid in favor of some other sources that put them into a more modern framework that obviates any need to reference these specifically except perhaps as historical footnotes or extra reading.
Modern philosophers tend to be extremely dense and difficult to read. What I'd recommend is starting from the beginning - key works of Plato, such as Apology (the trial and death of Socrates), Republic (an ideal government, and Symposium (a friendly conversation about the topics of the day). These are all quite readable and enjoyable, and frankly as good as or better than most modern works.
I agree with you, though, it seems like this language issue is a roadblock to many. The same could be said of mathematics and science, and most of my own learning has revolved around breaking through the initial barrier to entry to a given subject that's in the form of its technical language and notation.
