"Up for grabs" is one of the first projects to do this on a wide scale in Github and that I absolutely recommend for starting contributing: https://up-for-grabs.net/ https://up-for-grabs.net/ The reason is that it's opt-in (instead of ML-found issues), so the authors of packages have expressed a strong willingness to help first-time contributors. I've used up for grabs before (as an author) and it was great.
