Yeah, got bitten by that a few times my self. In stead of naming the view model SomethingSomething*ViewModel*, I typically create it in another namespace, so the model is eg.

using ContentModels = MyProject.Models.ContentModels;
namespace MyProject.Models.ViewModels;
public class MyOrder : ContentModels.MyOrder
{

And then in my view I have

@inherits UmbracoViewPage<ViewModels.MyOrder>

instead of ContentModels.MyOrder. I think it communicates efficiently that this view is relying on a custom view model, without having the long class name
