Typically you should be settling with some specialization in mind. If the terrain is mostly flat or coastal these make great food towns. If the terrain is more rough then this could be a better mining (gold) town.
Also consider what the town would be feeding. As mentioned above it's difficult to grow in antiquity at high pop counts if you don't have good growth bonuses (Khmer, Confucius etc). So if it's late in the age and the town would be feeding a high pop city (I wish you could direct where the food goes) ? Probably do another specialization and reconsider in the next age (you can switch at each age) or leave it on growth using the 50% bonus (which effectively double the food the town is receiving).
Similarly to growth bonuses, gold purchase bonuses make the value of gold rise up making mining towns more attractive if you have them.
By default (without much purchase bonuses), the production -> gold conversion of productive towns is a bad deal (You get a 1:1 conversion but you buy stuff at a 1:3/1:4 ratio) so I would always consider converting these highly productive towns when they are at high enough pops.
The jury is still out on what exactly is optimal, the above just puts down some things to consider.
