Double Sharps and Double Flats
Hey, y'all! I'm running through inversions of basic triads (maj, min, aug, dim) on the keyboard and was wondering how people refer to double sharps and double flats in the cases of augmented and diminished triads. Curious to get perspectives to have a better way to internalize note names.

Take for example an augmented chord (1 - 3 - #5)
For C#: this would be C# - E# - G#(#)
I understand that G## is technically the right note name, even if the enharmonic equivalent of A (which is a b6 vs a G## being a #5) looks simpler. I do somewhat agree with the reasoning, since it keeps chord tone qualities consistent.
My question is this the correct way to think about it?
You could also refer to the C# as a Db (Db - F - A; no double flats), but I'm curious about the case of C# in particular since I'm thinking of this in the case of keys and sheet music notation e.g. if you're in a song that's A harmonic minor and you truck driver's gear shift up to A# harmonic minor, the III chord goes from C aug to C# aug (not Db aug).

Similar question for the case of diminished triads, how would you think about Db diminished (1 - b3 - b5), which would be Db - Fb - Abb.

And maybe most importantly do people have an easy-to-distinguish, monosyllabic way to refer to double sharps and double flats 😅? Saying "##" or "bb" for note names when on the keyboard as an exercise is exhausting.
