Actually, you've just reminded me that some scholars prefer the tetralogy approach of Thrasyllus. The Republic's designated tetralogy is Clitophon-Republic-Timaeus-Critias, so you could give Clitophon a go (its very short).
Alternatively, I found pic-related when searching for the tetralogies https://www.plato-dialogues.org/tetralog.htm. Its quite a different arrangement and I don't know who by, but it reflects how there is no agreed consensus on how to approach Plato's dialogues. Besides, you'll find that the dialogues you've already read will reveal more upon re-readings after tackling some of the other works, it unavoidable really and there's no point fretting too much about approaching Plato in the 'optimal way' or something.
