Conversely, when I use a PC, I have to stop and wonder why alt-R doesn't reload the web page like it's supposed to, and alt-C doesn't copy, and I have to stretch my pinky all the way over to use that shortcut. And what's the mnemonic for "F5 means reload"?
Which is to say that neither Windows nor Mac shortcuts are inherently better. It's just what we're used to. IME, the main difference is that once you learn the Mac shortcuts in a handful of apps, they'll pretty much work on the other apps you encounter, too.
Ctrl-R reloads the page in every browser that I have used, so perhaps that's what you're looking for.
A big issue with the macOS style I'd that there isn't a modifier key free for the user to build their own shortcuts around. The Win/Super key is a very good place to hang custom shortcuts off of on Windows and Linux.
