Expected
use cache should be able to use in sitemap.ts to create a static sitemap.

next dev (local), next build (local)

Additional context

Setting dynamic to force-static instead of using use cache doesn't seem to have any effect, properly due to dynamicIO being enabled,

I had the same issue, had to remove use cache from the functions needed for generating the sitemap for now.
