Oh yeah, I would entirely forget about the continent map for now, ditto for story quests. You've got some city work to do! First up, get your tech buildings up to date.
Colonial has a nice small footprint Clockmaker for supplies -- ditch the huge HMA farm, the EMA stuff, the LMA stuff. You could place a few cheap Bronze Age Blacksmiths to help with the event produce supply quests. Colonial is one of the nirvana ages for heavy questers, but you don't have to be one to benefit from doing some recurring quests while collecting your city. But do try it out, you may find that you like it and get the itch to find Chateau prints lol.
Get your military up to date. Is that a little Ygg? Get some levels on that bad boy. Ignore any advice to the contrary.
Zeus will help, it's small and cheap to level, but no secondary benefit. Next one should be CdM imo, and it gives fps.
There's so much space taken up with cultures and decos for happy I want to gnash my teeth! If you have to have them, go for the biggest and the fewest you can get by with-- each of those little decos sucks up a motivation that could have gone to productive use. Don't forget you can upgrade roads for a bump in happiness.
That's just a start; going forward, others have given good advice. I'd just note that there's not much FP production showing. No SoKs? Event FP buildings? Something to think about. You're going to want an Arc at some point, and that GB has quite the appetite!
