I’d really like minor illusion to have some more of the utility it can have in a tabletop game. Another common use besides drawing someone’s attention is to create a 5ft cube (i.e. a crate/box etc.) in front of yourself or an ally in trouble and stand behind it to gain (partial) cover. As far as I know, the most common ruling is that an enemy must attack, miss and then see through the illusion or spend an investigation check and beat the spells DC (as per spell description) to see through the illusion. If not the penalty from half/full cover applies. (Truesight and such would of course also bypass it)
As for Prestidigitation, now that everyone gets super dirty after one fight, it could clean up a targeted character. Or make someone clean look dirty. Also, instantaneously lighting or snuffing out a Candle, a torch, or a small campfire from range can be useful as well.
