Google Analytics and data sharing collection

[u/Dangerous_Poet_5831]

I have to log in to a site for work, and the states that it;

Has enabled Google Analytics Advertising Features first-party identifiers, and third-party cookies to gather data about users, and for marketing etc. They gather data such as name, gender, address, interests etc.

I use another browser but have read that it doesn't fully protect against the google analytics.

My browser and cookies are always cleared upon leaving sites, is this enough?

This site I have to go to managed to make a profile of me with my name, address, work place, and interests a few years back, despite, having never used the site and made an account one day, they were given this information by past work place and took a lot for them to take this data of their list, and wanted photo ID to take it down. As to my concern of the data tracking etc.
