I am currently working on a citizen request portal for a county government highways department. I originally started with the Citizen Reporter instant app, and limited submissions to a buffer I had made around the county roads. This worked just fine, but we decided that when someone attempts to submit a report outside the buffer zone, instead of just being their submission is not allowed we want them to be prompted with the contact information for the town/village that the point lies in, which is a different layer. Would this be something that a mix of survey123 and field maps is better equipped for?
