What happens to the shifter cable/housing when the brake lever is squeezed? Do they move fore/aft with that action? Are they stationary? Does that cause additional stress for the cable?

Obviously nothing or you'd end up w/ your derailleur shifting every time you braked.The brake lever pivots separately from the shifter.

Yeah, that change-out is way too frequent. Hopefully you eliminated all other culprits.
Mine works out to about a once-per-year chore. It's far less about the cost than the time.
Although, come to think of it, I replace my bar tape every other time. That stuff is expensive.
Cxwretch: please tell me where to find the $4 high-quality cables.
Imagine you get for dealer cost, so send me a batch and I will repay you.

After this you'll get nothing from me.

QBP lists Jagwire Sport SS shift cables (CA4444) for less than $4 dealer cost, these would typically retail for $5-$10 shop dependent. I suspect cxwrench doesn't use coated cables, as I don't too. Andy

In that case we buy cables from QBP and our cost for SRAM is less than a buck when we buy a box. Shimano is a $1.50 so we sell both for $4.00/ea retail. Standard stainless steel cables. We sell Optislick for $8.00/ea. And this is in Marin County, so our labor prices are pretty high but we don't gouge people for product.

Damn. My local shop sure sticks it to me. Part of our discrepancy here is that I always buy in pairs.
Still, that's like $18 a pair for regular Shimano, non-optislik. (Those never work right for me.)
Oh well....part of the price to pay to patronize the LBS. Along with CO2's, tubes, lubes, and other smalls. lol

The Experimental Aircraft people have a rule-of-thumb that in order to prevent eventual fraying of a control cable, any pulley/guide/direction change on a cable should have a radius at least 50 times greater than the diameter of the cable. I can't see that fitting inside a modern shift lever, and I suspect that's why Shimano makes those routine replacement recommendations. At least, failure of a shift cable on a bicycle isn't likely to be as catastrophic as a control cable failure on an airplane.

They charge $9.00 each for standard Shimano Stainless cables?!? Are they pulling them out of a file box or are you buying individually packaged cables? Even then they shouldn't be that expensive. If your shop won't sell them for a reasonable price screw em and get them online.
