App specific folders in iCloud Drive - eviltoast

I haven’t been able to find good info on this, or it could be that there’s nothing to speak of.

New to MacOS (last time I used it was c. 2001). My intention is to use it as close to “as intended” as possible, including using all of Apple’s productivity apps. I also have an iPhone.

I am using iCloud Drive and have Desktop and Documents sync turned on. When I used Pages for the first time it made a Pages folder in iCloud Drive.

I know I don’t HAVE to use it (I can open docs in the Documents folder and its subfolders from either device) but is there any special advantage to using the dedicated Pages or Numbers (etc.) folders that I’m not seeing? Or am I missing out on nothing by ignoring them and filing docs where I want to. TIA!
