Medium and paper go together along with your desired effect. A good paper for charcoal is not necessarily good for graphite. Since your example is pencil I'll focus on that. If you look at pencil drawing books from the late 19th and early 20th Century they recommend a heavy weight smooth paper like Bristol, but they are also teaching the use of the pencil to do crisp line work, essentially treating the pencil like an easier to use ink pen. They actively discourage scribbling and smudging relying almost exclusively on hatching for shading so they want a paper that will produce solid lines. Later pencil books from about the middle of the 20th Century to the present tend to teach a much broader use of the pencil and these also recommend a wider range of paper types to fit the particular style. Smooth for heavy line work, and something with more roughness if you are going to shade, smear and smudge the graphite. Charcoal needs a rougher surface to help hold the charcoal, and ink tends to work better on a smooth surface. Graphite is pretty forgiving on paper type, but will produce different effects based on the paper surface. It pays to experiment. Small sketch books and single sheets of paper are nice for experimenting with media and paper combinations because they are cheap, so you can easily play around with different combinations.
