With a border pop, you can claim silver & wine with a single city. Worth it ?
Monument can be a 4 turn build if a worker is on duty.
I'm not familiar with the tech path in isolation but Monarchy seems like a no-brainer to me, here. Cottages, wine...
Agree with Fippy @ Pottery first.
^ Maybe I say so because I dabbled with the map and settled 1S, getting a 3rd floodplains in the capital.
Actually went 2nd worker at size 4 before 1st settler. Chop 2x + whip. Repeat and rince for 2nd settler.
Whether it's better to stagnate the capital only 2 turns or to put more overflow into the granary is a question that I don't have any answer for.
@ Second worker :
It delays the 2nd city, for sure, but I would think this is made up by an easier development.
It becomes rather easy to chop into a 4 turns workboat,
and then it allows to have 30 hammers into the granary at early size 2 to whip it.
Downside : you burn more forests.
@ Lain :
I had a peek at your 1000 BC save and Library in Tokyo before the workboat for the clams seems strange.
I suppose you were worried about the low happy cap ?
