If weight is the measured effect of gravity on an object, and gravity is stronger the closer to the object’s center of mass the measuring object is, do objects high in the atmosphere weigh less than those on the ground, from a physics standpoint?

Yes, but the difference isn't very big. The radius of the Earth is about 6400 km (depending on where on Earth you measure). So if you're 10 km high in the atmosphere (the cruising altitude for long haul commercial aircraft), you're only 0.15% further away from the center of mass.

Since gravity is proportional to the square of the distance, that means there's a difference of about 0.31%. On a fairly average adult male of 80 kg, that's about a quater of a kg difference. This difference is certainly measurable, but it's also well within daily fluctuations of ones weight (a drink, a meal or a bathroom break could cause differences of similar magnitude).
