There are a lot of settings that can get modified by cookies. One example is the cookie-setting for allowing nonSameSite-iframes: https://docs.mendix.com/developerportal/deploy/environments-details#iframe

document.cookie = "originURI=/login.html" + (window.location.protocol === "https:" ? ";SameSite=None;Secure" : "")

The name and values of the properties that you set in the cookies get defined by the application that uses them. That is the reason why you will not find one single page listing all possible properties and their possible values.
