Instant pot is your friend if you don't want to learn. Plop in any meat with some water and push the button. Super soft meat and then you've got a delicious broth

That is what I do what all of the other roast cuts, but rump roast felt like it needed to be roasted and sliced thin like roast beef. I actually used broth that we rendered from the soup bones in the roasting pan, and then covered the roast. Adds some delicious flavor.
