The big one for me on Mac was refreshing a web page being CMD+R rather than F5.
Not to mention the muscle memory for pressing CTRL in the corner of the keyboard rather than CMD where Alt is.
Though I will say that having "Copy" (cmd-c) being different from ^C (ctrl-c) was kind of nice. Though Terminal has done a nice thing of making it so if you highlight text, Ctrl-C copies the first time you press it, and sends ^C the second time.
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.

It's not like you can't change it.
System Settings > Keyboard Shortcuts > App Shortcuts > add your browser > remap the Reload menu item to F5
Along with Karabiner you can pretty much make Mac OS work however you want it to when it comes to keyboard shortcuts.
