Halevai
“But a phenomenon which is not a mark of creation, nor a consumption of Hashem’s world, but an effect, doesn’t elicit a Bracha. In what way did you encounter Hashem’s hand now more than before? In fact, there are many enjoyments that we don’t bless Hashem upon enjoying them.”
Your explanation is a bit arbitrary, and seems forced to fit the conclusion.
Why isnt an eclipse part of creation? Who then set the sun and moon in motion?
Why is The blotting out of the sun midday less impressive than an earthquake?
which category does earthquake fall into is it a mark of creation or a consumption of Hashem’s world? It doesnt seem to fit your narrow criteria
ditto for a shooting star/comet ?
Chazal said those get berachos and eclipse doesnt, so be it, but your categories seem a bit forced
