Actually, no, the Standard Edition Deploy Server Wizard does not prompt you to choose how to install the SQL databases. The Location for Database Files screen will ask you where on the local hard disk(s) you want to install the database and transaction log files, but these are for the locally installed instance of SQL 2005 Express.
If anyone knows of an undocumented switch or procedure to deploy Standard Edition using a separate, remote instance of SQL and NOT automatically install SQL Express, then I'd like to hear about it. So far my research has turned up no way to do this. I'd assume that installing Enterprise Edition is the intended and supported answer, by design. A Standard Edition server is meant to be a consolidated deployment, but you can simply install a single-server Enterprise Pool to achieve this, which I have done in production deployments.
