If you accept the equivalency principle of ma=F=mg, then "weight" is the total sum of forces on an object to keep it un-accelerated in the local coordinate system. That would mean that the buoyancy force is absolutely part of it, and the weight of an object within water is less than the weight of that object outside of water...in fact, a floating object has zero weight.

I think you need to have another think about that.
I disagree that weight is the total sum of the forces, it’s one force, yes.
