Group volunteer ideas for ~10?

I’m looking for suggestions for a group volunteer/philanthropy event for about 10 people. In the past we’ve done the food bank, which was great because it was super organized, easy to plug into, and well set up for groups.

We’re hoping to find something similar — structured, impactful, and relatively simple to coordinate for a group that size. Ideally something that can accommodate us all at once rather than splitting up.

Any ideas that have worked well for you?
