I think it's a step too far to assume all chakra modes are the same. I disagree.

Above all, a chakra mode is a technique, one that enhances physical ability and defensive abilities. The lighting cloak the Raikage use is essentially a lightning chakra mode. Doesn't mean he has special powers.

Kurama is able to generate a battle avatar, even now that the two halves are joined. So i think it's clear it's Kurama's ability, especially since Minato could use it too, even though he's not an uzumaki or transmigrant or secret senju.

Susanoo is a specific battle avatar and a Kekkei Genkai.

Eighty Gods Vacuum Palm similarly creates a battle avatar, but only around the hands. Naruto essentially does the same with Kurama's chakra. I don't see why Kaguya can't extend it in every direction to form a true susanoo-like construct, other than the fact that she's already pretty immortal.

Now, Adamantine chains is a bit of a weird ability as it's marked as Hiden in the databooks. Only Uzumaki seem to have it and e.g. Karin was able to use it in her anger, without a hint of training it or anything. The whole scene seemed to imply it was a power (perhaps not unlike Susanoo) that awoke, not a secret jutsu. It makes sense to be Kekkei Genkai, but it's not a huge hole in any reasoning or trend either.

Tenseigan grants a chakra mode. It mostly does what chakra modes do, enhanced defenses and abilities. I don't see anything special.

The Ten Tails is still a biju, and Biju grant chakra cloaks(version 1 and 2 cloaks). Obito and Madara using it while being it's jinchuriki isn't that special.

Finally, Naruto's cloak in The Last came before SPSM was locked in, and i think it's fairly clear that the mode is supposed to be SPSM. In Naruto Gaiden and Boruto, Naruto's cloak changes with his clothing (and for some reason his seal changes shape too). In Boruto he has a form with and without the Hokage cape. In Gaiden he has a different outfit. It's got nothing to do with modes and links, it's a cosmetic/convenient thing.
