Is there a compendium of where applications store their defaults?

We are trying to find out where the System Preferences stores the information for file server shares that you add to the Users & Groups>Login Items list. But to widen the topic, is there a place/website where one could look up an app and see all of its dependent files? I understand that most applications store their settings in their com.XXXX.appName.plist, I more want to know where the OS stores its settings.

Not sure if there's an official full listing of what gets stored where, but in the case of user level Login Items, these are stored in the com.apple.loginitems.plist in the user's Preferences, so

/Users/username/Library/Preferences/com.apple.loginitems.plist

Though these days you can manage them via Config Profile which is going to be the preferable way, rather than trying to manipulate the user's plist.
