Plato's Timaeus and allegory of the cave are worth reading but the neoplatonic ideas that influenced both the Church Fathers as well as Augustine, Anselm, and Aquinas are best acquired by reading, Augustine, Anselm, and Aquinas. I don't know of any Evangelicals who are also Platonists, believe that eternal immaterial forms are the source of causal origin of all that exists. Aristotle was co-opted by Aquinas to suggest such were the ideas in God's head, but no need to put Aristotle ahead of Aquinas on the reading list.
Given that we all are limited in our study time, cultural contexts like Ancient Near East (ANE) Literature from 2600 BCE to 330 BCE would be a better use of one's time as it sets the context for the OT.
Similarly, NT Culture from the Seleucids through 100 C. E. would be equally helpful.
Modern philosophers like Alvin Plantinga, Marilyn Adams, Robert Adams, William Alston, Keith Ward, Nicholas Wolterstorff, Richard Swinburne, J.P. Moreland, John Lennox, Peter Kreeft, Jacques Ellul, Roderick Chilsome, William Lane Craig, robin Collins, Paul Copan, Ed Feser, Dallas Willard and Francis Schaeffer(sure I have forgotten dozens) are all more impactful and practical than Plato or Aristotle on our current Christian philosophical foundations. So it is a matter of prioritization.
Often ideas such as impassibility, or the ineffability of God are seem more like philosophical baggage rather than reasoned inferences necessitated by God's nature.
Note: (Should have given a trigger warning to our Thomistic friends here on CF, mods please don't send me a "flaming" warning for saying "seems like philosophical baggage," please, no really, please).
