When you tap the Share icon—to open a dead link on an Archival website, to strip a YouTube link of the si tracking parameter, to Force Select All on a webpage—you see your iOS/Siri Shortcuts listed at the bottom.

As I should have known, re-arranging them is simple. No need to scroll to the bottom, edit actions, add to favorites, and drag around—unless they really are favorites.

No, instead, just open the Shortcuts app, tap Share Sheet, and re-arrange there. DUH!!!
