The full 8’ would need to be in contact with earth. Drilling a 3/4” hole in the concrete floor would mean a longer rod.

I'm probably short for a convincing debate, but i thought part3 of art 250 did not require Grods in lieu of a Ufer....~RJ~
Many designers think it's necessary to have every type of GE imaginable including triads, octagons, squares, kitchen sinks, etc.....

Locally that's the only "glitch" in the plan. When the rod is installed through an interior slab, a 10ft is often required to meet 250.53(G)

That and I suppose if we are going to be picky, there should be 2 at min of 6' apart.

To comply with code - not much, drive a second rod and don't even bother to test resistance and you have met code.

Well the CEE is not required, but if it is present must be used. In existing construction you don't have to use it if it isn't readily available to connect to though.
Ground rods are never required, but are typically first choice if no other electrode is present or a condition requiring a supplementary electrode exists.
Code compliance or not, rods inside or outside won't amount to much regardless of what their resistance to earth is.
