Interior wall paint texture

I am attempting to create a texture for an interior wall made up of paneling, however, I think the default diffuse node is a bit… bland.

I want there to be a little texture to the wall, but I don’t particularly want to try to UV map this, anyone have any ideas on how I can best achieve an interior wall texture? Doesn’t have to be anything specific, but maybe like a concrete and drywall (textured).

I am wanting to achieve something like this

That is exactly what I was looking for! Thank you.
