If I were capable to travel to the end of the universe, what would I hit or see?

Travel through distance to somewhere the universe "ends" (where there is no more universe)? Or travel through time to when this universe dies?
Distance answer. Not possible. The forefront of the wave of creation started by the big bang is too far away now. And because of that great distance, the "edge of the universe" is moving faster away from us than the speed of light. How can it move faster than light? The edge itself is not moving faster than light. But all the intervening distance is all expanding. The distances between each galaxy are growing because of the property of expansion of space. By 72 thousand kilometers every second for every megaparsec of distance. And the rate is getting faster, due to "dark energy". So the edge of the universe goes away from you and me faster than the speed of light. Can never catch up, since no matter or energy can go faster than light. Bye, bye. Then you grow old and die.
Time traveling answer. As far as going through time, you would not have to move. You would not hit anything. Something from outer space might hit you. Or the sun swells and consumes Earth. If you are still alive, you die. The end.

You would hit a brick wall with a sign on it saying, DEAD END.

There is no such phenomenon.

Your point of beginning. A nominal 2D universe would be like the surface of a BALLOON. You end up where you start from as you go around it. Note there exists ONE MORE dimension (the third) than what the "living area" of a universe has (in this case, TWO Dimensions)
A nominal 3D universe is the same thing plus a 4th dimension.----While a 2D universe is really a 3D sphere, a 3D universe is really a 4D HYPERSPHERE. we eventually will return to our starting point after we "go around the other side" if we travel far enough. Like the 2D inhabitants, they cannot perceive the 3rd dimension. As 3D inhabitants we cannot perceive the 4th.

The universe has no end or edge or boundary. That would violate general relativity. Space is either infinite or finite but unbounded. It could be the 3D surface of a 4D hypersphere.

Given it would take you 39 billion years,,at the speed of light no less,,not only would you be a tad older, what you would most likely see is,,just more universe.

The size of the universe is measured by the light that reaches Earth. Since no light means that's the end of the universe (or close to it), you will just be traveling into a dark void. Of course, your body and your spaceship will be ripped apart in a second and scattered into atoms.

The top of a petri dish. This whole universe thing is just a huge experiment in a much, much larger world.
