I would love to be able to see which sensors were used for a particular activity, and to be able to label those sensors in Garmin Connect, so I would know which sensor provides HR, Cadence, Sped etc.

The data response from the server shows the following data in the subset "sensors" of the JSON structure, when you open the URL https://connect.garmin.com/modern/proxy/activity-service/activity/4792409645 (replace the numeric Activity ID as needed). Hope it helps.
"sensors": [ { "sku": "006-B3287-00", "softwareVersion": 8.1 }, { "sku": "006-B3287-00", "localDeviceType": "BAROMETER", "softwareVersion": 8.1 }, { "manufacturer": "WAHOO_FITNESS", "serialNumber": 4294914475, "antplusDeviceType": "HEART_RATE", "softwareVersion": 4 }, { "antplusDeviceType": "BIKE_SPEED_CADENCE" }, { "localDeviceType": "BLUETOOTH_LOW_ENERGY_CHIPSET", "softwareVersion": 0 }, { "sku": "006-B3294-00", "localDeviceType": "SENSOR_HUB", "softwareVersion": 4.2 }, {} ],
