Here's my thinking for a street car. You spend more time driving in the 2000-4000 rpm range than in the 4000-6500 rpm range. It's kinda the same as flow numbers, you spend less time at .600 than .300-500. BTW, I have a flat torque curve with a BTR stage 2, 227/234 cam that starts pulling from 2000 rpm to 6600 rpm.

And the extra power in the 3000+ range feeds into me being perfectly content to sacrifice torque in the lower range... it's circular reasoning it its finest.

If I want to pass someone, or enjoy an on-ramp, I downshift to get the revs up. Partly because the gearing change works in my favor all by itself, and partly because trading off low end torque for midrange torque makes that downshift twice as rewarding. So I feel like torque around cruising RPM is way over-rated.

I, like you, thought the cam came in good at 3200 where the converter stalled. Then I swapped to a 4k Yank converter, and man was I wrong. The car felt so much better in the midrange, proving the cam was much better with just an 800 rpm increase. Engines just have limitations, to get somewhere you give up something somewhere else. There is no shame in having a little less torque to get your high rpm power where you want it. It's a balancing act and as long as you are happy that's all that matters.
