I won't run CF bars (no need to get into that here) and have used aluminum forever with steel forks. As I've aged, I've made a concession. I now wrap my bars with two layers of tape. Fizik on two bikes, cloth on the rest. All my bars are relatively old-school weight and thickness. Nittos or other Japanese makes. Nothing "high-strength" or light.
I rode 70 miles of gravel last weekend with ~6000' of descending. No hand issues at all. In fact, Monday morning I couldn't even feel my chronic issues. (Now I do take real care to optimize bar shape, bar rotation and lever placement to minimize numbness which I do get if my wrists aren't cocked just right.)
