Science
When I entered the Industrial Age in 960AD I decided not to bring Russia and Korea forward. I was at war with Korea and wasn't willing to make peace yet. Gifting Russia forward would only give me a 1/3 chance of getting Steam Power, at the high cost of giving my rivals a chance to build some of the wonders I wanted. Better to keep them back in the Middle Ages.
Steam Power was a priority so that I could build railroads and increase production in my 20K city. I learned it in 1010AD.
The next priority was Industrialization so that I could rush a factory and coal plant in my 20K city. I learned Industrialization in 1060AD and in 1160AD had my factory and coal plant. Ta-tu was now up to 84 shields/turn:
I continued research at the fastest pace I could to get through the Industrial Age quickly. It doesn't enable many wonders, I'd need to reach Modern Times to make more of them available to Ta-tu.
I was nearly able to maintain four turn research and entered Modern Times in 1395AD.
I was a bit slower in Modern Times, not able to maintain a four turn pace. But it wasn't necessary, I was able to stay ahead of Ta-tu's ability to build wonders. At 1640AD I turned off research. I'd learned eight Modern techs by then - six to enable all wonders except Strategic Missile Defense, one to enable Mass Transit, and one to enable Modern Armor.
Warfare
I was still at war with Korea when I entered the Industrial Age. That war continued until 1050AD. By then I'd booted Korea off the mainland and I gave her peace for two island towns.
In the meantime I attacked Russia again as soon as my peace with her expired in 970AD. I also gave Russia peace in 1050AD, for one town.
My world map at that date:
I controlled the home continent up to China's wall. I also had holdings on five islands. Russia and Korea were down to one town each, both on the same island which they shared with one of my towns.
I didn't need to fight anyone after this. My 20K date would probably be about the same whether I continued expansion or not. I already had all the resources I needed and had six local luxuries.
But I couldn't resist expanding more. I used spare production capacity to build Keshiks and waited for someone to learn Military Tradition. When that happened in 1410AD I traded for it, upgraded my 33 Keshiks to Cavalry, and began an invasion of China. As this war began I shifted production to tanks and they soon became my main force. I allied Japan in this war and we destroyed China (Japan eliminated a last settler somewhere) in 1480AD.
In 1500AD Japan declared on me and took a few towns. My retaliation was swift of course and when I gave her peace in 1535 she was down to one Island town.
Along the way I eliminated Korea and Russia when peace with them expired.
Next I attacked Vikings and reduced them to two towns by 1605AD, taking silks along the way. This war was fought with tanks, many of them air lifted to the other continent.
I was at 57% of the world's land at that point and didn't intend further war, planned to just expand borders to claim more land. But Portugal foolishly attacked me in 1655AD. At this point I had a large number of Modern Armor. I took some of Portugal's cities, including taking dyes as my eighth luxury, then razed the rest and eliminated Portugal in 1690AD. At the same date Celts eliminated Japan and I ended the game with them and the Vikings as my only remaining rivals:

And in 1774 Ta-tu was past 20K culture and I got a culture victory.
My Jason score isn't much in this game. I focused on building up Ta-tu at the start and was way too late building up my core and invading neighbors to get a high score. I also delayed later on, waiting for AIs to learn Chivalry and then later on to learn Military Tradition before I started wars. Here's hoping my focus on the 20K city has paid off
