https://www.comixology.com/The-Legend-of-Wonder-Woman-2015-2016/You can also easily find a pirated version of the collection edition on line on innumerable sites.
Is pretty easy to follow and reasonably accurate to the comics. Once you read that, you can check out the Perez and Rucka (both two volumes each) collections. Your library should have them and they might even have a digital service, or you can buy one (the Rucka is more modern, but Perez is what many people know). Your library, if they have YA books/GNs at all, will probably have the current Rebirth run and you can get to that afterwards, if you are still interested.
With Batman you can read the GA archives, those are also on line as pirated editions or they are on sale through the holidays at the DC Entertainment site, you can download digitals. Not sure if the hard backs are on sale physically. Your library should have those. The Year One volumes should help if you want modern stuff and again, library should have them.
Krypton is probably the hardest. Secret Origin and Birthright are the two best Superman origin books but both barely touch on Krypton. When Superman was seriously rebooted for the first and only real time, John Byrne did write a few mini-series about Krypton but I don't know that they are really in canon and I doubt you can find them in print or at your library.
Last Son is probably your best Zod related book, but it's barely a bit of that and has been retconned a bit (for example, Zod is apparently wondering around the current DC comics universe but barely there).
