Response times. I know they are more difficult to track, but a little
logarithmic histogram might be doable.

Probably doable.  What do you think of the output of iostat (here is default iostat output)?

$ iostat /dev/nvme0n1

Presumably nfsstats are not any more helpful - here is sample client stats output from nfsstat

$ nfsstat -c
