This blog states that we can make Web Api work in CRM on-premise (non-IFD) plugin by using WebClient with DefaultCredentials.

using (WebClient client = new WebClient()) 
{            
    client.UseDefaultCredentials = true;
    byte[] responseBytes = client.DownloadData(new Uri("<your web api url>/accounts(3C2D2712-E43F-E411-9402-005056AB452C)")); 
    string response = Encoding.UTF8.GetString(responseBytes);
    // parse the json response 
}

Make sure you specify the UseDefaultCredentials as true to make the web api call under the context of the user the plugin is running.

We may struggle more with Online plugins because of Sandbox + Adal library + AAD tokens combo as we are trying in a non-interactive plugin code unlike other interface where we can challenge the user by prompt.

Moreover Web api is more useful for cross platform, outside CRM context integration. Inside the platform execution you can use Org service to achieve more.
