Open Lists > Place List and run Geocode. It will automatically assign Lat/Long and Standardized place name to those that do not have geo-coordinates and that it recognises and will present you a list of those that it is uncertain about for you to pick a possible match. Not a report per se.
You could generate Reports > List > Place List with the settings "Print all places in the database" and "Print latitude and longitude if entered". Look for those places lacking lat/long - they probably do not have a Standardized Name. It is possible that you might have manually geocoded a place and not entered a Standardized Name.
Otherwise, it's another SQLite query... for example, Places - Frequency of Use.
