You will get fuzz on cross grain cuts. There isn't any getting around it but sharp bits can lesson the amount. An easy way to remove it is to stand the fuzz up by using a stick moved against the way the fuzz is leaning, pulled down the length of the cut. Then you use a sanding block, sanding in one direction, it only takes one stroke with a fine paper, 220 +-. In these pictures of a dado with fuzz on both sides, I do one side at a time, stand up the left side, sand one stroke from right to left, opposite on the right side, the fuzz will be leaning the other way. Once the fuzz is stood up, you can cut it off with a sharp chisel too but you run the risk of it cutting into the work piece where it will show if you aren't careful and the chisel isn't real sharp.
I used to teach a beginning woodworking class. For an initial training project we would make a simple Shaker coat rack, nothing more than a board with pegs and an edge routed around the perimeter. We started with rough stock and went through the milling process which allowed me to cover all the basic woodworking machines. It would take three weeks to make the simple rack since I would thoroughly teach the set up and safety procedures for each machine along the way. When we routed the end grain, everyone wanted to pull on the fuzz to remove it, kind of funny since this was the case with every student over years and I always told them not to touch it yet, we would get to it later. It just bugged them and they would start pulling on it, often pulling back fibers where it would show.
