One potential shortcut is if you install their CubeMX and take a look in it's data files there are XML files for each distinct peripheral. So there'll be something like RTC_v1.0.xml and RTC_v2.0.xml. Someone uploaded an old copy of them [1] if you just want a quick look.
Then there's also device & device family xml files that link to the various peripherals they have [2].
There's probably no guarantees but in my experience if two devices link to the same version xml file their peripheral registers at least will be identical. Quirks and silicon bugs, you are on your own of course... but then the ref manual doesn't help with that either!
