My web application typically will be installed to use applicationPoolIdentity:

<iis:WebAppPool Id="MyAppPool" Identity="applicationPoolIdentity" Name="MyAppPool"/>

but I have a class of users that will want to use a specific domain user instead, which I would typically author like this:

<util:User Id="MyUser" Name="[MY_USER]" Domain="[MY_DOMAIN]" Password="[MY_PASSWORD]" CreateUser="no"/>
<iis:WebAppPool Id="MyAppPool" Identity="other" User="MyUser" Name="MyAppPool" />

Making the user interface for this is simple enough, but is there a way to conditionally switch between Identity="applicationPoolIdentity" and Identity="other" without writing a custom action?

Yes, it is possible but you will need to create a component group with two components that have conditionals. As this solution is a bit verbose, I recommend having it in a separate file.

Here is an example, based on https://www.codeproject.com/Articles/115036/Creating-WIX-Installer-for-ASP-NET-Web-Application.

        <Property Id="IIS_WEBSITE" Value="root"/>
        <Property Id="VIRTUAL_DIR_VAL" Value="myappdir" />

        <!-- +++++++++++++++++++ web app name properties initialize ++++++++++++++++++++ -->
        <Property Id="WEB_APP_NAME" Value="myapp" />
        <Property Id="WEB_APP_USE_CUSTOM_APP_POOL_IDENTITY" Value="1" />

        <!-- +++++++++++++++++++ app pool identity properties initialize +++++++++++++++ -->
        <Property Id="WEB_APP_POOL_IDENTITY_DOMAIN" Value="domain" />
        <Property Id="WEB_APP_POOL_IDENTITY_NAME" Value="user" />
        <Property Id="WEB_APP_POOL_IDENTITY_PWD" Hidden="yes" />

        <!-- Reference to IIS Website to install to, but not create -->
        <iis:WebSite Id='rootwebsite'
