We had a new fence installed last week - it is 6ft cedar planks, board-
on-board, 8 foot, u-channel steel posts, mounted in concrete.

The fence looks fine, but it doesn't seem as solid as I expected. I
can push it with one finger and the whole fence moves (the movement is
probably as much as 4" back and forth at the top of the fence). It
just feels like someone could push it over fairly easily if they
tried. With steel posts in concrete, I was hoping it would be quite a
bit stronger, more rigid and resistant to movement. I'm not sure if
the posts are bending, or perhaps the concrete foundations weren't set
properly or are not big or set deeply enough, which is causing the
lack of stability. ...

Either get someone else to watch while you push or you watch and have
someone else push and you can easily determine where the movement is

If the posts are moving in the ground, may be able to tamp it in and
the ground may settle back in and firm up w/ time if dug out larger
than the volume that was poured. OTOH, if just poured a little 3-4"
thick cap at the top, or something similar, maybe there isn't
sufficient support.

If the posts are fixed relative to the ground and the posts flex,
sounds like you got a cheap post and the only fix would be to use a
better post.

I agree w/ the other poster, a well-built fence of the type should be
"pretty solid"...
