I'm much more intrigued with how much "older" the Earth continued to get, after Darwin found a wide audience.

I believe it increased from estimates of 1-2 billion years old to the current estimate of 4.6 billion years old. It was already several orders of magnitude older than the the 7,000 year YEC theories before Darwin.

I don't understand why an increase in the estimated age of 2-3x after Darwin would be more significant than the increase of 600,000x before that.

Your numbers do not match my recollection. Let’s not go cherrypicking an outlier, here. Widespread scientific acceptance of even one billion years, did not predate Darwin.
