I think the main benefit of Blazor (server side) is that it's very easy to write SPAs with it. This is great for incompany apps that don't have a lot of traffic (Blazor can be difficult to scale). You bind your backend to your frontend and SignalR communicates all changes. But there are some things you should be aware of. Because the frondend and backend are integrated it's very easy to 'leak' your data layer to the frontend. Always use viewmodels.
