In a curved orbit, that may be true at points, but for an extended object, tidal forces come into play:

Orbit is free fall. It’s equally correct to describe a falling object’s weightlessness as moving as fast as gravity.
> get why this 'feels' like weightlessness/0G, but does it actually have that impact when it comes to physical manufacturing
No, it’s the first postulate of Einstein’s theory of special relativity [1]. Free fall and the absence of gravity are as indistinguishable as acceleration and the its presence.
