Protestant churches will vary, but I grew up in the American South, where religion is at least ostensibly important (and a major cultural fixture in the past, though less so today). Usually one or two morning services and some kind of Bible study in the evening on Sunday, and Wednesday nights usually had Bible studies and a sort of mini-service.
Other nights featured smaller study groups, athletic activities (a lot of casual adult sports like softball are organized by churches), or special events like musical performances, choir practice, etc. And then there's the daily pastoral care (officiating funerals, visiting the sick, etc.). But in the absence of Eucharist as a frequent component of worship, and where confession and last rites aren't even considered sacraments, there's little fundamentally different between a well-run Bible study and a full service except the scale. The actual things done aren't really different.
Note: Episcopal services would be much more familiar in structure to a Catholic mass, and I believe Lutherans are similar (but, y'know, not a ton of Lutherans in the South, so I can't speak with any authority on the matter).
