Tropica is slightly annoying. No acorns from oak trees, no juniper berries from juniper trees, no wool from sheep, no pigs, no dozens of other things that can't be produced over 25C. I wonder if winter time brings down temperatures under 25C. And I wonder what winter is. Is Tropica considered southern hemisphere, so wintertime is what would be midsummer on the northern hemisphere?
What you need are coconuts, cork oaks, nutmeg (especially nutmeg), and I guess bananas are okay if you have loads of them. Then set up some fruit growers (about one per 50 trees) with the cheapest baskets, set them to automate, and sell the goods to Space Venice. Nutmeg only grows in the jungle, however, so you'd need to set up a new domain for that.
Besides fruit-like stuff, you should also convert that meadow to hay fields. It means building and demolishing loads of barns, but it's decent passive income. Then there's all those pine trees you have. Pine wood sells reliably for 10-20d per [m3], so each tree can net you a few hundred deniers each week. When you have hundreds of trees available, that's easily tens of thousands of denier each week. The downside is you cut into your income if you use it as building material, so you might want to harvest lesser woods such as palm to avoid that.
Linen doesn't do well above 35 [degC], so maybe don't grow that unless you absolutely need it for something else and can't afford to or don't want to buy it. You can reliably grow hemp and convert to rope for slow but reliable income, but to do that in large quantities requires sanity-draining micromanagement if you don't have relatively expensive ploughmen.
Supposedly there are more tropical themed goods in the works for currently useless things like bushlands, banyans, and kapoks, but given schist has been around for longer and is still useless, don't count on it happening anytime soon. (Then again, sulfur became useful.)
You're about 6000 arpents north of the equator, so you're headed into summer, though you probably won't experience much seasonal variation there.
