For C6H4, why are the two C atoms that are sp and not sp2 constrained?

That's because they have a triple bond between them so they have 2 electron domains= sp1

In the ring shaped structure there are not enough hydrogens to give those two carbons another atom attachment. Therefore there are only 2 regions of electron density around those two carbons (electron density doesn't care if it's a single double or triple bond) with only 2 electron density regions the rules for hybridization state that those 2 carbons are sp. I would look at the lewis structure online, it clears it up even better.
