In Modern Forms, using the LFForm object, is there a supported way to retrieve the label of a selected checklist item?

I can retrieve the selected value, but checklist values are restricted. They cannot contain special characters or start with numbers, which makes them unsuitable for storing data such as email addresses. I also don't want to maintain a JavaScript mapping or complex formulas to translate values back into labels, especially since the checklist changes frequently.

Ideally, I'd like to maintain the options entirely within the form designer and have my JavaScript retrieve the selected labels directly. Is there a supported API or recommended approach for doing this?
