Custom search result type layout for SPO list element / hyperlink and people column

The customization of search result types seems to be poorly documented, so I'd like to ask if someone ever managed to include values from a "SPO managed porperty" linked to a Hyperlink column (explicitly the URL) and a Person/Group column (explicitly DisplayName and UPN) to a custom result type layout.

Is it technically possible to access different values within such complex columns / managed properties and display them in custom result layouts (custom JSON)?
