Given the Father has superior knowledge, authority and power to the Son and their relationship is described by both is father and son, I should think “inferior” is a suitable and accurate term.

Suitable used in the military-sense, yes.
Unsuitable in the evaluative sense, as Jesus said "the Father and I are one", and so cannot be of a lesser quality.

(Like a glass of seawater, being [the same] seawater, is not inferior water to the sea; but a glass of seawater, being smaller than the sea, is lesser than the sea.)

Value was not the point but power, knowledge, authority.

Jesus explained in John 17, particularly vs. 22 what that the being “one” was that he and his followers enjoyed and he prayed for.
Vs.22 “....that they may be one just as we (praying to his Father) are one”.

That oneness was not in a godhead or such but purpose and actions, etc.
