The hero stories you're describing are stereotypically individualistic. That's fine insofar that it shows that each person is capable of greatness, but there are also inspiring stories that don't just feature a single hero (and his/her journey), and I'm not just referring to the Justice League.

There are stories that feature multiple protagonists and each have obvious strengths and weaknesses. When they band together, their strengths offset each others' weaknesses, essentially forming a singular (yet, collective) heroic identity.

These stories are neat in that they don't just instil lessons on personal growth, they teach me how to work with others to accomplish something great while growing together, as a group. They teach me that it's important to help others, and at the same time, that's it's OK to reach out to others for help.
