We recently did similar work for our pipelines, heavily based on Better GitHub Actions caching for Go [0]. Were you aware of that article, or did you (re-)discover things like the cache trimming?
What's the best way to contribute? I'd like to expose the "go-version-file" input for the setup-go action instead of setting a Go version directly. Open an issue in the repo?
Also, have you considered this potential optimization: the module cache doesn't care about architecture, it's just downloaded code. Would it make sense to cache module and build cache separately, and use an architecture-free cache key for the module cache?
