Correspondence (matching theories to observations) is a subset of coherence (matching everything with everything)
Correspondence is not just matching theories to observation. It is matching theories to reality. Since we don’t have pure transcendent access to reality, this involves a lot of matching theories to observation and to each other, and rejecting the occasional observation as erroneous; however, the ultimate goal is different from that of coherence, since perfectly coherent sets of statements can still be wrong.
If your point is that “reality” is not a meaningful concept and we should write off the philosophizing of correspondence theorists and just focus on what they actually do, then what they actually do is identical to what coherentists actually do, not a subset.
As far as I can tell, most coherentists want to match theories with reality too, because truth doesn’t really have any other useful definition. The goal is not to be coherent within a random and reality-detached set of sentences: the goal is to be coherent with the whole of science. When a scientists rejects (assigns very low probability to) the observation of a perpetuum mobile on the basis that it contradicts the laws of physics, that is a standard coherentist move. This is another one. The goal is to avoid having to waste time and costs on non-fruitful data gathering. Ultimately the only thing that is rejected is that blind data-only approach that may be considered the straw-manning of the correspondenceist position, except that one is actually unfortunately used too much. A coherentist will simply not spend money buying an airplane ticket to check if someone’s garage has a dragon, the proposition contradicts so much we already know that the very low prior probability does not worth the cost. You may as well call this a wiser version of correspondencism, the barriers are not exactly black and white here. This is unfortunately philosophy, so fairly muddy :)
You can have holism without coherence where you require that the whole of science is true by correspondence, but the parts aren’t.. Inasmuch as it is correspondence, it isnt coherence.
The correspondence theory of truth is a theory of truth, not a theory of justification. Correspondentists don’t match theories to reality, since they don’t have direct ways of detecting a mismatch, they use proxies like observation sentences and predictions. Having justified the a theory as being true, they then use correspondence to explain what it’s truth consists of.

You’ve got coherentism confused with holism.
Is holism even a thing?
Yes. So is Google.
