Pull in value to radio cards

How can I tell my radio field card how to pull in the parameter_id in a front end post edit form? I’ve got this working in a radio loop using {acf_background_color:value:{url_parameter:id}}. The loop does a post query for an ACF meta field but it’s a convoluted setup.

To simplify I figured I could create radio options for each background color I want to have available (no loop). When I create a checkbox wrapper with set values, I’m not sure how to get the checked item to show. What /how do I need to query? Current settings attached.
