I don't know in detail how apt works, but IIRC (sorry if I'm wrong), in a previous discussion of this it's been suggested that the difference is apt doesn't refresh this data unless you explicitly ask it to, while dnf does automatically refresh it on most operations, depending on a refresh time specified in the repository configuration (this is several days for mostly-not-changing repos, but more like a few minutes or hours for update repos which change frequently).
Yes update (refresh metadata) and upgrade (update packages) are separate operations with apt. Even the updates repository has a 6 hour refresh interval in F31 though so it shouldn't have to refresh every time - the base repository has a 7 day refresh interval. A refresh initially only checks the top level repomd.xml though, which is tiny - it will only carry on and fetch other things if they appear to have changed. I wonder if Bill is running dnf as a normal user rather than as root so that it is using a per-user metadata cache that will have to be created if it doesn't exist yet. Running as root, even for operations like list that don't really need it, is generally better as it can use the shared system cache. You should be able to use --cacheonly to stop it refreshing, or indeed use --refresh to force a refresh. Using --cacheonly will also make it use the system cache even when running as a normal user.
