To integrate Workfront with AEM you need to utilize the "value" of a custom form (back-end name) instead of the "label" (front-end, user friendly name) because AEM requires a formatted string to feed the data.
This has an impact inside of Workfront on calculated fields as the calculated fields return the "value" (back-end name) and not the front-end name that users see. For example if you have a Region dropdown, the calculated field would return "regional-coverage/701782" instead of "US."
There is not a way to reference the dropdown option's label (front-end name) rather than the value (back-end name). The only workaround is to use a series of IF or REPLACE statements that generate a string equal to the label (front-end name) for the dropdown selection. This becomes highly cumbersome when there are a lot of options to maintain (a country option alone could have 195 options) and even more difficult when there is a multi-select field.
The ability to define whether or not we want to return the label or value would be beneficial and help to more seamlessly complete a Workfront & AEM integration and in general.
