My strategy is to build my national wonders for short to medium term effect. I actually had no good GP farm location other than Delhi, and sacrificing some cottage growth and beaker output to run scientists with NE was beneficial to the civilization as a whole by getting more shrines and academies.
Then with Oxford, I knew Delhi was a better location long term, but Madras could finish Oxford before Delhi was even done with a regular university, and I want the research boost now to get the midgame techs that boost my whole empire like Biology, Computers, Assembly Line. Wall Street, I built in a different shrine city that had good production, again while Delhi was still working on a bank.
I obviously got somewhat lucky with all the trades available because of the AIs sharing a religion, since each tech traded for saves a couple of turns at the end and there's no risk involved in the trading. (If your base tech rate is higher, being 3 techs ahead at the endgame is just as guaranteed a victory as 10 techs ahead) Also, a benefit of tackling the Scientific Method branch of the tech tree first is that the AIs generally like Democracy and Rifling as renaissance tech goals and you get more trades.
Overseas trade routes are more lucrative than mercantilism if the AI is willing to trade. My coastal cities are typically pulling in trade routes of 7/7/6/6 with harbours. If there's about 30 foreign trade routes and you lose (conservatively) 4 commerce from each dropping to a domestic trade route, you're out 120c. Mercantilism only gets you back the equivalent of 90 of that for a 15 city empire. Then of course free market gets you 15 more domestic trade routes worth about 2 each, so I think it's easily ahead here.
