I mean, the only dumbest moment when Naruto used SPSM was against Shin, and actually he didn`t use any SPSM ability. He only used Kurama`s chakra to protect Sarada and ChoCho. Against Momoshiki was understandable why he used it.He had to protect the entire village and afterwards he fought a TTJ level + opponent in Momoshiki (Kinshiki absorbed).

In the Last he did display plenty of BASE form feats that justified his abilities without power-ups.Besides that, he only had a brief encouter against Boruto so that he can test the artificial tech-hand that can absorb ninjutsu.

Oh yes, and another dumb moment to use SPSM was when he caught that bandit in the anime. But you can make the argument that he only needed the speed required to catch the trainn all the way from the village.
