Thanks for the PR!
I would remove the if check for the GitHub repository owner and run on arm as we do for amd64. I mean removing:

          if [ "$GITHUB_REPOSITORY_OWNER" = "apache" ]; then
            echo "," >> "$GITHUB_OUTPUT"
            cat <<JSON >> "$GITHUB_OUTPUT"

and reorganize the code to a single JSON write.

LGTM

Could you remove the docker-targets job? Could you define matrix in the docker job statically? We don't need to define matrix dynamically now.

If you want an example from what @kou suggests you can see this diff on the main apache/arrow repo where the docker-targets was removed for a matrix:

Sure @kou. I'd love to help here, and Thank you @raulcd for pointing me in right direction

Done. Let's trigger the runner for testing.

Could you keep these keys in alphabetical order?
