As explained in First-Party Data Activation

A first-party cookie is a web cookie created and controlled by the site owner for recognizing users or sessions within that owner's own interactions and infrastructure.

A first-party cookie is a small data packet generated, updated, and read by the website domain a visitor is currently viewing. It can preserve session context and help connect anonymous activity to a visitor’s account after sign-in. section 6.2

Common uses include:
