Man, I've been down this rabbit hole lately. The classic one everyone mentions is 'The Rising of the Shield Hero'. It fits the bill perfectly, but I gotta say, its character growth can get pretty cyclical. Naofumi's whole thing is this slow, painful burn from bitterness to a sort of guarded heroism, and the revenge elements are deliciously cathartic, especially early on. The justice part is more about personal vindication than sweeping societal change, which I actually prefer—it feels more grounded, even in a fantasy setting.
If you want something with a more methodical, almost chess-like approach to revenge and growth, 'The Count of Monte Cristo' but manga-ified, check out 'The World's Finest Assassin Gets Reincarnated in Another World as an Aristocrat'. The title's a mouthful, but the MC's progression is all about cold calculation turning into something with purpose beyond the mission. The justice is delivered with eerie precision, which is super satisfying in a different way.
