The real meat of what CI/CD does is closely tied to the platform, I don't think there's a great way to improve that. Running on different configurations, uploading artifacts, deployment, etc.

Generally, I do as much as possible in the build system proper. The CI should mostly be running simple commands. Avoid GitHub Actions which can be trivially replaced with one or two shell commands (which is a lot of them).

It should be more achievable than it has ever been before with container tech being in a great place, qemu being a thing and the webassembly ecosystem getting better every day.
