From a typical user’s perspective, macOS puts all Preferences files into ~<username>/Library/Application Support/<app bundle name> or ~<username>/Library/Preferences/<app bundle name>, and they are standard Plist files readable by both command line and GUI tools that ship with the system, so easily editable and human-readable. From a power-user’s perspective, it is a Unix system and that part of it is the usual mess of Unix config files. I’m definitely a power user but rarely have any need to touch a Unix config file on my macOS systems.
