M&M 3e was exactly what I thought of when I saw the title. I think it works well as a split for dexterity.This roughly matches how Mutants and Masterminds 3e broke them out - Agility and Dexterity (as in hand-eye coordination). They also broke Strength out into Strength/Fighting to separate brute strength from ability to land a blow in melee. That's a bit more on-point for a superhero game, but the breakout of the two big combat stats seems to work pretty well.
Sleight of Hand
To Hit Ranged (and melee if finesse)
Edit: Fairly importantly, the big offensive (attack roll) and defensive applications (AC, saves) don't sit with the same stat.
