A cheaper paper that has an almost identical paper white compared to VFA (and Photorag, German Etching, etc) is the Canon USA Premium Matte 210gsm. Falls in the CAD qualities and may be obsolete right now, was only available in North America. Some ads show a much lower price now. While it has a similar paper white the ink itself can still behave differently on its paper coating and deliver another gamut.
Epson Enhanced Matte 190gsm or whatever it is called now is also better than your choice of proof paper. Slightly cooler though.
Paper profiles describe the color gamut of a specific ink printed with a specific driver media preset on one paper only. The rendering choices fit the image in different ways in that color gamut based on the image's color space. If all the image colors fall within both the paper profiles gamut then a choice for relative or absolute colormetric rendering could make the prints more alike but usually that is not the case and one selects perceptual or relative colormetric to get a nicer image that will not represent the original totally but is at least in harmony in itself.
