A good overview for installing SQL Server and great to point out that while using a single service account isn’t ideal it can be acceptable for a scenario like this.
The only part I would change is that running SQL Server under an account with administrative privileges is opening up an attack vector and should be avoided no matter what the scenario. I appreciate this is only a home server but I would strongly recommend using a standard user account. A standard user account is of even greater importance given that each service is using a shared account.
Thanks Jason for your comments and overview of my article.
As pointed out in Note 4 in my article I do acknowledge not using another account for the service account would normally would not be advised. However, If the home server owner wants to create another account spefically for the SQL instance out of thier pool of 10 to replace the administrator account than they can do so.
But, if they need that 10th account for another user the administrator is still the better alternative than the guest account since the guest account is easier to be broken into if enabled and in some ways can be more dangerous than the Administrator account.
Again, thanks for the comments.
