We did dance class at a rec center. They also offer gymnastics and archery. Some have singing/acting/drama/art classes. We found our Girl Scout troop through school. We're lucky that our school has a good amount of extracurriculars, so all are through there now.
As a single mom, I just tried to find the most affordable version of what it was she wanted to do. I used Google and asked on Facebook (both my own network and in neighborhood groups).
Check your neighborhood (general or parent focused) Facebook group. We’ve gotten a lot of leads on activities from the South Silly Facebook group (parent/family focused) for things in South Philly.
And check the Rec centers outside your neighborhood as they all have something different to offer.

Your local parks & Rec, school, public pool, and library should offer different programs
