I missed the recommendation for Golden Age and I second that as well. Even though it's an Elseworlds it works as a psuedo prequel for both Robinson's Starman and Johns/Robinson's JSA run.
I also really liked Waid and Kitson's since-retconned JLA Year One which similarly updated a prominent DC "Justice" team for a new era.
