The Chicago series is pretty great. It's a bit dated now, but still worth reading.
But you might like Roche's selection of 10 plays:

It's a little loose, but very readable. It doesn't have all of the plays you're looking for, but maybe enough to serve as a gateway.
I've always found Roche pretty readable, and this is an inexpensive book with a bunch of plays (including Medea): https://www.amazon.com/Ten-Plays-Signet-Classics-Euripides/dp/0451527003
