Cuba is not a problem for a non-US citizen as long as you don't fly there to / from the US, and not on this ticket. But if you want to go from Mexico or Canada as many people do, it's a non-issue, they won't even stamp your passport so no evidence of your visit. I know plenty of people who have been to Cuba on non-US passports and visit the US quite regularly.

The Sudan ban has also been rescinded, but a stamp may still draw scrutiny from CBP officers when they actually look at your passport. But these days they rarely even open mine or my partner's (mine is US, hers is Japanese). They primarily just use the facial recognition now.

As for your itinerary, I assume you're waiting until WY joins before issuing it (CDG-MCT)? You only have 1 stopover in Asia so that restriction is not a problem. But I'm pretty sure you have too many segments in Europe / ME. I cout 5 there, you'd need to do one of them as a surface segment or drop AMM or DOH. Those are quite reasonably priced in economy with either AA miles or Avios, but for business (first) only AA for QR flights, but either AA or Avios are fine for an RJ flight. For QR, both BA or QR price it as First, not business and the cost is outrageous. I'd likely recommend doing MCT-AMM as your surface segment since AMM-DOH on QR will grant you Al Safwa lounge access.
