But I just found a lovely quote which I wanted to share, and it's in the midst of sermon prep, so not time-wasting.
Derek Kidner on Psalm 110 mentions in a footnote those who dispute Davidic authorship:
The majority of present critics dissent more moderately from the New Testament
view of the psalm by seeing it as an enthronement oracle for either David or one
of his successors, spoken to him by an anonymous cultic official. Our Lord and
the apostles, it is understood, were denied this insight.
