Cursed seal is related to Sage Mode, since Jugo's clan has the innate ability to absorb Natural Energy, so since the Cursed Seal comes from Jugo, then it is related to Senjutsu too thus Sasuke's Chidori used in part 1 was a Senjutsu technique
We've seen then Sasuke using a Black Chidori using Rikudo's chakra, same for Kakashi... However in the fight against Deidara for example, his Chidori never turned black despite using the cursed seal
The speculation that cursed seal mode is sage mode is basically 100% canoon. I mean if you look at sasuke's face when he is in curse mark form.
and look at the markings when his susanoo is under Senjutsu influcence.
IF we assume that a person's senjutsu markings are unique to them, then its clear that the cross shaped senjutsu marking that appeared on Sasuke is due to Senjutsu enriching his chakra. The mutated appearance of Sasuke when in the Cursed mode sort of goes back to how Jiraya pointed out that if a person is unable to properly balance Senjutsu internally with their chakra then they create an imperfect sage mode. And they take on animalistic physical properties. Since cursed seal form isn't a naturally occuring sage form, it makes sense that the mutations don't look like any animal in particular. Just a combination of random animal characteristics.
Kakashi had senjutsu when he preformed his black lightning cutter... kamui thingy? He mentioned that his power had gone up because of Obitos eyes, which had been under the influence of perfect sage mode and were enriched with senjutsu. So him using Senjutsu powered black lightning also made sense in the context.

There isn't really a fire to add fuel to. The whole point in starting this whole thing was to point out that black lightning all across the board has something to do with Senjutsu. Maybe not a specific mode, but at least the very use of the chakra. That goes for cloud as well. With every instance of black lightning having something to do with Hagaromo or Senjutsu it being somehow some different mechanism for the cloud seems highly unlikely. It also helps that the cloud is the only village aside from the leaf to have an affiliation with Hagaromo in the form of his sacred tools.
Kakashi's raikiri was powered by the traces of rikudo chakra that Obito still had left hence the black form. If he just mixed different chakra types (which he couldn't by the way) it wouldn't matter since only senjutsu, taijutsu and rikudo chakra would work on Mathew juubi's jinchuriki.
