Nope, not the IV-B, but the IV which only flew on the Saturn I.

Which would have made a wicked looking 100MT ICBM. I know, I know,
Saturn was a civilian-only program.

Not exactly silo ready either.... heh.

Since the RL-10 was abandoned in favor of the J2 was there anything of
use in this flight other than testing of the Saturn I first stage?
For example, the avionics package, tankage and pumps, ullage, the helium
purge?

This was the first large LH2/LOX upper stage. So I believe that it was
pretty much an engineering pathfinder for the IV-B. It provided
experience with designing, building, and flying a large LH2/LOX upper
stage. I'm sure the lessons learned went into the IV-B.
