I think it's probably better to study on paper, as you don't have an instant un-do function, and therefore have to be more attentive to what you're doing, and that's just one of many small cheats that you can do digitally that could hamper your studies (should you use them).

That said, studying digitally now and then isn't bad, because you don't want to become rusty at drawing digitally and end up having wonky unconfident lines.

So I guess I'm saying; why not both?

not really, that's what makes them fundamental.
but "doing the real thing" helps, so use the medium you actually want to use.

Learning to draw is a cumulative process where you build little by little and put everything together in your final artwork
Having only pencil and paper simplifies things, allowing you to focus more on what matters and learn more easily
Starting digitally is a big leap suddenly, many things appear on the screen, options, brushes, layers, setup
If you are an absolute beginner, like level 1 or level 0, go with paper
If you are an advanced/intermediate beginner, use both

If you want to practice something general like form or shading, it's less about which tool you use, it's about you focusing on the aspect of the excercise you want to improve at. If I try to copy complex shapes for example what I want to train is my brains ability ot visualise and understand the form. It doesnt matter if I draw that form with a huion or finger paint, I still learn how to understand form.

Getting better mechanically at using a real pen/a tablet is something you should practice either on it's own or just get as a byproduct of grinding fundies unless you're the kind of beg that has trouble with drawing a straight line. Try to think about what the excercise you're doing is supposed to teach you and try to mostly focus on that aspect to learn effectively. Like the point of drawing boxes for example is to expand your brains 3D model library with boxes from all sorts of angles until drawing them becomes automatic, it's not supposed to teach you how to keep your lines straight and pretty.
