Can't argue with your first two points (Wouldn't be a consideration for me personally, but I can understand)
The third however should hardly be a consideration as it's not even a 2 hour flight to IST, compared to around 4 hours to ZRH, so even if you don't get the proper C (which you might) it's hardly a big deal.
Edited to add: Not to mention that you never know whether LX may decide to sub the L/H craft for a S/H one...
