Yes, the PDF linked by mrm2007 is on the Nucleo product page.
It's called the user manual , last PDF on product page.
I have to agree with Kjelt. This topic has tendency to turn into "where can I find this pdf, its not on the page, much complicated, so sucks". Try to be more resourceful. We all went through the same hoops, it's not going to change a thing between vendors because it's all the same but with a different flavour of sauce. It's not ideal, but finding a way through the system helps.
And yes Microchip/AVR will have the same thing. If you look at a recent PIC24 or PIC32 datasheet, it wont tell much specific about the peripherals anymore. It is in a separate document. Maybe if you're lucky a brief overview of the registers are in there, but it does not explain in an animated way what each bit does.
Atmel used to publish summary datasheets for their parts. That can be confusing as well.
Overcoming 4K difficulties: maybe try Windows magnifier?
I know it sounds stupid, but in XFCE on Linux it has the magnifier hotkeyed to ALT + Scroll. If my eyes are fatigued, I'm sitting far from my screen (like chair back is all the way down), or just plain lazy, it's so helpful.
And no I don't even have 4K or 1440p that is.
