The only way for you to know how the cookie will bake in your oven is to test it.
Convection is extremely high dry heat because it concentrate all the heat around a single rack. It really is not suited for home baking. Convection was designed for commercial baking in which multiple racks are filled with multiple pans or full sheets of product.
The type of bakeware will also effect your final product. anodized aluminum, coated bakeware, and dark metal will conduct heat more intensely. So product bakes drier, browns faster, forms a hard dry crust.
Example of how bakeware effects product. Same batter, same oven, baked at same time. Only difference is the cake pan. The cake with that hard dry crust is baked in a Fat Daddio anodized aluminum pan. The loveky soft white cake was baked in a uncoated plain metal pan. Choose the right pan as well as the right temperature.

Thank you, NorCal Baker. I am so glad you posted about the pan differences. I knew that darker pans cause more browning, I didn't know about the anodized aluminum. All of my cake pans are Magic Line, either solid or removable bottom, I LOVE those bottoms! I bought a Fat Daddio pan once, and I hated it because it had rounded corners. I love the square Magic Line. My cookie sheets are also uncoated aluminum, no sides.Volrath, with no sides. I love those as well. I baked my cookies at 375 for 7.5 minutes, they were perfect for ice cream sandwiches. I found yet another recipe to try, from Cooks Illustrated, and THAT recipe is even better than the rolled sugar cookies, so I am going to test that one in different size pans. Funny, but my 11x17 pan, which is suggested in that recipe, is the anodized aluminum. I think I will re-think using THAT pan, as I don't want browning on my ice cream sandwiches. May not see it on the chocolate cookie, but certainly the texture would be crusty and perhaps a little burnt tasting. I think I would rather bake 2-3 scaled batches rather than one huge pan of cookie that has to be cut up, as I might have difficulty getting such a large thin sheet of cookie out of a such a large pan. Thank you again for your help!
