1000-1500 mm (40 to 60 in) is ideal for me: enough for a proper forest (assuming warm temperate/subtropical temperatures), but not enough to reduce the sunshine amount by too much.

Same here, and that's what we get here in Sammamish, WA, about 53" / 1,346mm average, and that's what keeps it green here all year. I have yet to water our lawns this season, and they are nice and green still. The difference is that we also have much less sun, the rain is usually very light, over long periods of time.
For me it's more about the nature of it that matters. I generally prefer briefer, heavier rain to light persistent rain. The annual quantity isn't as important. So I'll go for an average sort of 750-1000mm a year.

I can somewhat agree with you: but I will prefer one day of heavy downpour over one hour of a tropical cyclone/typhoon/hurricane delivering ~25 mm (0.98 in) of rain.
I grew up in California with about 20" annually, moved to an area that got 30", then to windward Hawaii, with a whopping 160" a year, then to Arizona, with only 10", (all during monsoon, and I wish it would start, already!)
Next up, Oregon, so I can have more rain!
