You can do all of them when you use a Mac, but Apple will do a lot to try to persuade you not to. That means you'll spend a lot of mental energy fighting with Apple's very effective p̶s̶y̶c̶h̶o̶l̶o̶g̶y̶ marketing department, and often you won't win. That's fine. You don't really lose anything, but every so often you'll think to yourself "I listen to the same bands all the time" or "I wish this phone had a bigger camera sensor." and you'll regret putting so much of your life, and money, in Apple's pockets.
Honestly this is by far the biggest problem I currently have with newer versions of MacOSX.
I would have hopped by now that integration with dropbox, Sharepoint/Onedrive, Google Drive would have gotten better. But they are mostly barebones.
Granted Google Drive is barebones on nearly every platform.
I'm a big 365 user, and that is by far the best experience so far in terms of fluid use between devices and apps. Especially on windows, where even sharing a file doesn't require a Web browser popup. But oh man the admin side of 365 is overly complex, and easy to see why people use gsuite.
iCloud Sucks and has always sucked. Unless that is you are 100% apple ecosystem. Integration into my onsite server is easy with 365, google, and dropbox. Icloud is super clunky and really thinking about moving the Wife to something other than iCloud.
