I haven't used Guix on my laptop much other than as a package manager or to work on patches when I'm not at my desktop. So I can't say much, but Guix does tend to be heavier on storage IO needs. You can always use substitutes to avoid much building, unless you are doing things you need to build locally, like custom patches or other changes. Proton I've only ran through Flatpak Steam. As I mentioned, Nonguix's Steam is limited to older Proton, but I think we'll get that fixed pretty soon once some bigger updates on Guix settle down (today was actually a "sprint" day to fix up changes coming to the main Guix branch soon). But yes, worked great in Flatpak. The main thing you'll miss from Guix in just using it as a package manager is the system configuration stuff. That will still be your host OS. You can play around with installing different things with Guix, package transformations, and even now trying out the (still in progress) Guix Home [0] to configure your dot files. Guix as a package manager will still give you a good feel of the advanced features it has for managing packages, without touching your host OS.
