In general, I think beginners are better off reading a good commentary or summary, at least at first. That is also generally the case across the board, across fields. Commentators with the background knowledge and scholarly perseverance can make the salient points of a work more conspicuous in a way a novice cannot. Read a few commentaries and sort of spiral in on the original work, if you really want to. It will give you knowledge and perspective that will make reading it more fruitful. Virtue law ethics and natural law theory are key terms. (David Oderberg has published some recent introductory texts [0][1] in this vein, but I have not read them. A well-regarded textbook explicitly in the Aristotelian and Thomistic tradition is Fagothy[2].) (N.b., Mieczysław Krąpiec, a scholar of Thomistic and Aristotelian thought and a colleague of Karol Wojtyła, once said that it took him 50 years to truly grok Aristotle. In my own small way, I can relate to this claim.)
