Why do you say that?
A lot of shortcuts are shared between windows and linux and fairly consistent across applications. Mac is the one that takes a decided "we're different" approach to shortcuts. I.e., Alt+L for address bar instead of Alt+D, Command swapping with Control, Q instead of W for closing tabs, Command+Control+Q for locking a computer instead of Super+L, etc
They didn't mention cross-OS shortcuts, though. I interpreted "across the operating systems" as meaning "across the various versions of Windows". Yes, Windows is more consistent with their own common shortcuts. But Macs have exceedingly consistent shortcuts across Mac applications, compared to my experience with Windows and especially Linux.
I might also point out that Mac had keyboard shortcuts before Windows existed, so it's not really fair to describe them as the "different" one when MS chose their own, different shortcuts for Windows.
Apple also invented their own key “Apple” now “CMD” for operation like copy / paste to explicitly not have the issue to overload the already know escape sequences. Windows being on a system without a normalized keyboard had to reuse keys that are common to keyboards used back then. Vertical integration played into apples cards even back then.
Aren't the Apple key and the Windows key just corporate branding on a super key?
The location of the command key is also a lot more comfortable. Thumb vs pinky.
I setup my Linux system to use it because it's more consistent for copy pasting in a terminal.
Many of those shortcuts already existed in macOS before they were added in Windows. Inversely, a lot of desktop Linux stuff was designed specifically to mimic the Windows behaviour.
So, really, it's Microsoft that decided "we're different".
Also, as somebody who sort of lives in the terminal, the lack of the Command/Ctrl distinction is one of the things that really bothers me about Windows. In default GUI applications, application shortcuts use Command, and Ctrl is used almost exclusively for headline-style shortcuts (ctrl-k for kill line, ctrl-a for home, ctrl-e for end, etc). Ctrl-a Ctrl-shift-e is kind of baked into my brain as "select whole line".
On the other, as a Windows desktop person I can't live without Home/End/PgUp/Pgdown, and in different combinations with Shift/Control. That's one of reason I can't fully enjoy MacBook, not to mention the incredible fact that it doesn't have a Delete key. No, it's not the same that you can use modifier key with backspace, modifier keys are used for extra functionality, i.e. to delete to begining or end of the word, etc.
Macs have every one of those, just with different shortcuts: https://support.apple.com/en-us/102650
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.
If you want a little more consistency for muscle memory, ctrl+L goes to the address bar on Windows the same way cmd+L goes to it on Mac. Same for ctrl+W and cmd+W to close tabs.
