If the Printer supported IPP "overrides", it might also be possible for a driver upstream of the IPP client to support this as a "driver feature" by adding a page to the start and/or end of the Job's Document and using "overrides" to specify the media source / type for the added banner pages.

There isn't anything specifically you can do in CUPS for the banners - it will use the same paper/tray settings for the banners as for the rest of the job.
There is a job-sheets-col attribute (defined in PWG 5100.3: Production Printing Attributes - Set 1) that provides more control. At present this attribute is not supported by CUPS.

What is the canonical IPP-ish way to request printing of a job-sheet on different media (or media drawn from a different paper tray)?
I remember many years ago to have hacked some PostScript files for a big institutional customer who required red separator sheets because thousands of their students shared a few dozen "public" printers: I then equipped the PostScript/banner files with some 'setpagedevice' statements, saved them to /usr/share/cups/banners/ and, presto, whenever such a sheet was requested it printed from the paper tray specified by setpagedevice.
Is there an IPP-defined job attribute that lets me order job-sheets to be printed on a specific medium?
Now that modern CUPS doesn't by default use banners/job-sheets any more which are PostScript files, what is another valid way to do achieve this with PDF files (or even with application/vnd.cups-banner files)?
