During the Silver/Bronze Age, Superman (across multiple media) often uttered such expletives as "Great Scott!", "Great Krypton!", or "Great Rao!" during moments of surprise or dismay. It was a convention of that era that largely disappeared after the Post-COIE reboot.
Would you like to see, within moderation, some return of this old Superman quirk? I feel his narrative "voice" has been missing something since he began eschewing these expressions Post-COIE. It doesn't need to be excessively frequent as it was in the past, but something we see at select, appropriate moments.
