If using vector is really important for you, the only way I can think of getting the crosshatch to work without being really tedious is by using the brush tool in illustrator (not the pen tool). You can basically just freehand lines that way, and change the type of line if you want different variances.
But to be honest, if you're not doing raster (or painting in one of those raster/vector combo programs) I don't think a cintiq would be a wise investment. I have a cintiq-like device and if I'm in Illustrator I still use my mouse for the most part.
Now, if you're fine inking in raster, with a program like photoshop, paint tool sai, clip studio paint, etc. then having a cintiq would be worth it because you're freehanding your lines. Over the years I moved completely over to digital for its versatility, and I actually find drawing traditionally to be awkward now and like I don't have the same finesse. So it really just depends on what you're used to. Spend enough time with a tool and it will become natural.
