Property URLs and potential conflicts

I would avoid changing the URL too much as you may end up in re-write hell and infinite loop. The address + id is a consistent URL that will not change which is important for sharing etc.

No problem using

ID+FULL_ADDRESS (best for SEO)

But you can adjust the title at import in WP All Import.

Our scripts provide the following

[epl_feedsync_format_sub_number({address[1]/subNumber[1]})]{address[1]/streetNumber[1]} {address[1]/street[1]}, {address[1]/suburb[1]} {address[1]/state[1]} {address[1]/postcode[1]}

You can adjust as needed.

eg

{uniqueID[1]}-[epl_feedsync_format_sub_number({address[1]/subNumber[1]})]{address[1]/streetNumber[1]} {address[1]/street[1]}, {address[1]/suburb[1]} {address[1]/state[1]} {address[1]/postcode[1]}

You could modify the slug but the ID will not be searchable or have a short URL as per your other topic as wordpress searches the title and not the slug
