I think I would avoid using ICore::settingsDatabase() if you have much plugin specific data, since it makes it hard to remove data that was created by this plugin and this plugin only. (If you have QSettings-like data, but much of it, you can of course consider using the class Core::SettingsDatabase for your separate data file.)

QStandardPaths has the disadvantage that Qt Creator’s “-settingspath” option will not affect that.
We usually use
Core::ICore::userResourcePath() + “/some_path_that_identifies_the_purpose/“ + filename
