Quick answer
Start with the Server API when your application has a backend, and use Script Tag when the browser should activate, render, and beacon a slot directly.
Callback and proxy patterns are narrower compatibility choices for integrations with those specific delivery or boundary requirements.
The API supports multiple integration styles, but the primary decision is simple: start with Server API for most apps, use Script Tag for browser-first rendering, and keep callback or proxy for narrower constraints.
