Shine or glossy
Some things will look better with glaze finish, some like matte more? Is it not all this way?
I always loved to print pigment rich thick 1-2 layer gums on non-seized paper (cheap acid-free Canson 120-200 g/m2). Later, after short exposition, I was developing prints with airbrush or "something stronger" (finger on the end of pipe is quite efficient water spray). This method destroyed all finest details and all tonal small things, but results was good enough (with subjects like ruined houses or some train landscapes), 100% matte prints.
If you start printing from pigment-reach surfaces, ending with almost pure gum layers for lights you'll get more glaze, that is my experience. Why not use gum solution to make glossy finish? Also addition of starch or fine diatomaceous earth or lots of pigment in gum will produce matte surface.
