Correct! You know how much interest I have in discussing that :P

I hadn't heard of this. Have you sources for this you can link to or provide?

Yeah, Bailey, Clube and Napier proposed in 1990 (Origin of Comets), that AD 400-600 may have been a time of increased bombardment risk due to a possible fragmentation event within the Taurid stream, evidenced by enhanced taurid fireball activity in observed astronomical records. So by invoking Solar Activity as a cooling mechanism, one appears to simply be replacing one contentious cosmic vector with a less contentious cosmic vector.

There are quite a few. See for example David Keyes "catastrophe that Carol has mentioned above, or Mike Baillie's Exodus to Arthur, or Celtic Gods. These tend to primarily discuss the 536/540 event, not the years after, but there is one record that is often dismissed as fantasy/allegory for the plague. Gibbon (1832) states


Such was the universal corruption of the air, that the pestilence which burst forth in the fifteenth
year of Justinian [AD542] was not checked or alleviated by any difference of the seasons…but it
was not until the end of a calamitous period of fifty-two years that mankind recovered their health,
or the air resumed its pure and salubrious quality .

Now it could indeed be reference to the abating of the plague (a belief that plague was caused by poor air), but it is interesting that Gibbon talks about the air being corrupted for 50+ years during the time when we know that large volcanoes injected a lot of aerosols into the upper atmosphere.
