My applications run on intranet/VPN behind IIS with Windows Authentication. If not WA, I would always choose Blazor Wasm, it gives you more control over what you do.

When building internal applications, you can make many assumptions - where are your users and how good is their network connection, how many of them do you have - dozens? hundreds? maybe even thousands, but not millions, so scalability is not a problem. Whether the app will be used on a mobile phones or not. Will it be a problem if your application takes 20 seconds to open? :) If the employee will use it half of the day, then probably no.
