Definitely! I like gardening. I started volunteering in a community garden, growing stuff for people who need more food. I like the people I work with, and I enjoy growing vegetables on a bigger scale than I can do in my own garden. And they make tea and cake, and often we get to take home some spare seedlings or whatever.
It's really great, it doesn't feel anything like "free labour", it mostly feels like hanging out with some nice people and doing a fun activity.
"Community garden" isn't quite the right term. It's actually primarily a food rescue organisation (takes unsold produce etc from supermarkets and redistributes it to poor people) that also grows a bit of their own produce as well, which is the bit I help with.
I happened to be at a kind of mini festival where there was a stand actively recruiting for volunteers. They seemed pretty surprised and happy when I immediately said yes.
The actual "community gardens" that I know of generally are on the model of members each have their own plot, which they tend. I don't know how one volunteers in a space like that, but maybe there are opportunities.
