I am always intrigued to hear what kind of soprano a conductor chooses for this movement. Maybe it’s whoever he/she can get, but I always hope that they choose a soloist for this song based on the sound of the voice and the soprano’s approach to the text.
Some sopranos sound a bit too grown up and worldly-wise for this text. I mean it’s a pretty ironic text, but I think the singer should sound a little child-like (maybe child-like with an edge) without actually sounding childish.
I think Miah Persson nailed it on this one. Listen and see (hear) if you agree.
For a contrasting (more ominous) interpretation from another beloved (by me)
soprano, check out this version with Dorothea Röschmann.
