Well, that kind of depends on your definition of "hero" doesn't it.
There are a few such entities in SF, mostly from the golden age works, which operate on the principle of Enlightened Self Interest. This principle is stated in varied ways, but the phrase "a rising tide lifts all boats" is a reasonably good starting point. Rather than attempting to dominate the economic or political power of the world these organisations work, sometimes secretly, to ensure that advances that would benefit all are made available to as many people as possible. A few such can be found in the CP genre, if you look hard enough.
They're not utterly selfless of course, in fact they're more selfish than the average. They just believe in the principle that more power/money/whatever can be gained if more is available in total. That the more money people have, the more they can sell to them. Of course their public image may not be particularly heroic, but at least they'll generally appear less bad than many of the others.
Then again there are those organisations that very carefully curate their public image to ensure that they are perceived to be The Good Guys, but hiding in the depths of their shell companies, contractors and other corporate skulduggery there are all sorts of rotten, despicable hidden things. Books and covers, I guess.
And then there are the Idealists. Without some serious backing these guys usually end up being eviscerated - hopefully in a corporate rather than corporal sense - by their less scrupulous competitors. Idealists try really, really hard to be above board, honest and honorable in all of their dealings, but they soon find that the game is rigged against them. Without a core of steel they're marshmallows in a fire... tasty if carefully done, but doomed nonetheless.
Other than that, you're essentially looking for a group that operates outside of a broken system. Hiro Protagonist. The Lo-Teks. Even Johnny Silverhand, although more so in his original back-story than the (quite entertaining) Keanu Reeves version from CP2077. There are plenty of edgerunners (hackers, street samurai and even a few fixers) who are out to fix the world, one corp-hack at a time.
Of course you have the occasional kind-of-good-guy powerful figure whose massive wealth and power have allowed them to make the choice to do good in the world. William Shatner's character Walter Bascom from TekWar springs to mind. It could be argued that Uncle Enzo qualifies here too... although it's kind of difficult to view Cosa Nostra Pizza as a heroic organization.
