The standard WebView2 installer is a tiny "bootstrapper" file. It downloads the required components from Microsoft servers during installation. However, the offline installer is completely self-contained. You need the offline installer for:
Consider an IT administrator managing over 100 virtual machines running Windows Server 2012 R2 in an environment with no internet access. They require a specific version of the WebView2 Runtime to be installed on all these VMs. The only viable path is to acquire the standalone installer for that specific version and deploy it via their enterprise software distribution tool (like SCCM or Intune) or a manual script.
Eliminating the UAC prompt during app installation improves the user experience, especially for lightweight or utility tools that users expect to "just work" immediately.
Some strict enterprise environments block the execution of unsigned binaries or restrict access to the default installation path ( C:\Program Files (x86)\Microsoft\EdgeWebView ).

The only place a license agreement appears is when you initially download the installer from Microsoft's website. This means that when you silently install WebView2 as a prerequisite for your application, your end users will not see a license agreement prompt. Microsoft's documentation encourages this approach, though you should review the licensing terms to ensure compliance for your specific use case.
