Join a hackathon that is focused on tech-for-good. For example, this one: https://www.fundingthecommons.io/hackathons
Firstly, mentors and advisors will help shape your idea into something that meets real-world needs. And then, if you decide, you could go through their Residency to turn it into an ecosystem-weaved project.
If you want something real quick... Just help an open-source project.
In general, your challenge comes down to two questions:
1. How big an impact do you want to make? What is more important - impact or time spent?
2. Are you looking to build a product or a tool? Products require more time. Tools you can build faster, but still would need to maintain if you want it to be helpful.
