An App Builder styling property is a feature that allows a Lightning web component to expose CSS properties that can be set by an administrator in the Lightning App Builder. This way, the administrator can customize the look and feel of the component depending on the context and use case.

The administrator can then change these values in the App Builder without modifying the code of the component. References:
