In straight wall cases, you can get a lot of things to work. Some that might not be a good choice in bottle-neck cases, but that's more for campfire chat. Rayon works, Dupont Fiber-Fill works, cotton balls work, Kapok works, you get the idea. The main idea is to keep the powder together as a mass and preferably down at the primer. I prefer fillers that displace as much air and compress the least for repeatability of shots. I've never seen a scientific study as to what exactly is the best choice to that end.
I do not use instant cream of wheat, nor instant grits. There are three main variations of grocery store hominy grits. There are straight grits. They take the longest to cook and in all cases, cooking is really re-hydrating. Anyway, there are 5 Minute grits. I believe they are a finer grind to speed up re-hydration. Then there's instant grits. I do not know this for sure, but I assume like instant rice, they're cooked and dried to open up the pores for even faster re-hydration. I've only used 5 minute grits because that's all the local grocery store carries. For eating, I like the larger granule, slower cooked, regular grits. I also like to eat whole kernel hominy, which I often had for breakfast long before I ever had grits.
The lion's share of grits that I've used in reloading were for fireforming as I don't shoot reduced power loads. I made some to simulate bullet expansion in water jugs at distances further that point blank range, but that's it, so please do not misconstrue my familiarity with making some with me having oodles of experience.

In Theory, there is no difference between theory and practice. In Practice, there is.
