If moving at the speed of light about 46.5 billion years.

Make note that it is reachable even though the universe is expanding because you’re not trying to reach a specific point in space, you’re just trying to reach the boundary at which is still theoretically observable from Earth.

If u traveled that far at the speed of light wouldn't u end up much further than that because of the expansion happening between u and earth?

It won’t matter where you are exactly, just that in principle, you could still be detectable from Earth before being red shifted into oblivion.

You’ll come up short of what’s there now and for you, your observable universe moves with you so we’re only referring to the observable universe with respect to Earth.
