Iron Working is very rarely a tech you want to self-research early in the game.
Jungle takes too many worker-turns to improve early in the game, swords are either inferior horse archers or very delayed axes, and as trade-bait it's pretty worthless because the AIs love to research Iron Working - you can't trade it to them often, and can usually get it from them fairly easily after Alphabet. I don't think this game is an exception. Iron Working is not the play here. Not 100% sure what techs you currently have, but I think Writing or Horseback Riding would be the next priority depending on how you want to play it out.
Points taken. I've advanced this quite a bit, here is turn 85.

I went the writing/alphabet path. With that done, I am seeing there are still a few civs out there without IW so I'm teching most of it with the plan to be a little short beakers and then get the rest in a trade to Churchill for mysticism. Then I can trade IW for the religious tech group.

Seven other civs here. England, France, Inca are or seem to be east. Portugal north. Zulu and Celts not visible but are almost certainly west. Arabs I think may be west as well.
With 6 cities there are five civs with only 3 so I think the growth rate is good. I'm thinking maybe two more cities and then take a breather in expanding to let the economy catch up.
The new cities all have a food resource in the BFC. That includes a pig for Uxmal, wheat for Mayapan, cow in Chichen Itza. City Z will probably be next although it will not have a food source. But that will complete the first ring for the most part.
Mayapan and Uxmal aren't in perfect locations as neither is on a river but again there is a food source for each and there isn't anyone to the south apparently.
