Each are data points that together contribute to your total fingerprint. TZP tells you a lot of these data points, and fails ones that dont match Firefox Resistant Fingerprint masked data. Creepjs does much of the same but without gearing towards Firefox.

Generally fingerprintable things include:

Do not track signal.
Private browsing mode.
Timezone.
Useragent.
Canvas noise.
Installed fonts.
Font sizes.
Browser built-in plugins.
Some extensions.
WebRTC.
Theme.
Cookies.
IP address.
Local IPs (website can execute an ip scan and fingerprint).
Window viewport size.
Full screen mode viewport sizing.
Page/font color settings.
Operating System (impossible to mask because of differences in rendering on platforms).
Browser App name & icon. System TTS synthesis engine.
DOM modification fingerprinting (like that used by many extensions). Mouse speed.
Keyboard behavior.
Stylometric fingerprinting.
And many more.
