If we limit the choices to the 5Diii, my most used (by a big margin):
EF 24-70 f/2.8 ii
Next is:
EF 100-400 mk ii
Followed by:
EF 16-35 f/4
Thereafter (about the same frequency):
EF 70-200 f/2.8 ii
EF 14 f/2.8
Least (only for birding and special stuff):
EF 300 f/2.8 ii which is my favorite lens even though I it does not get much use.
Go figure.
