If tonight (Tuesday May 14) becomes clear, Hesiodus A is target No. 1! Terminator is clear of it, but not too far to make spotting Hesiodus A easy.
Gambart J is also visible, and a similar distance from the Terminator as Hesiodus A. Contrast in the size between these two is the main thing, with Hesiodus A being 15km in diameter, and Gambart J being 7km.
Fontenelle D is right on the Terminator, so should be an interesting proposition too.
If you are looking for a very good lunar atlas app,
LunarMap HD is excellent. It shows and lists all of the concentric listed below too.
