The Pixel 5" meets the requirements, but it's still out of stock and $750(!). Otherwise the iPhone (same price) is the only other stock-OS, decent spec, <= 5" phone I'm aware of.

I have pretty much the same requirements (Stock-OS, Decent Specs, Not Huge).

With no love for apple, I recommend (from personal experience) buying an iPhone SE.

Edit: I mention the SE specifically because it is not the same price. $400 vs $750
