Whats best for SEO Options field or Refence field

hi im trying to setup a real estate website with tons and tons of listings. I will have one CMS collection called Listings.

These listings will be in various provinces and districts in Thailand. Now would it be better for SEO purposes that I use Options fields for the locations or Reference fields? I noticed CMS items have their own URL so I thought maybe referencing to a Province would be best but unsure.

Please advise.
