> She mentioned putting cardboard atop the soil, under the mulch.

Yes, I've done that, too. One problem I might mention, at least in this 
dry climate, is that squirrels would expose the edges of the cardboard 
as they dug in the mulch (which they frequently do). And once part of it 
was exposed, it would wick up the moisture from the rest of it. If you 
get a lot of rain, that might not matter. Here, it does, so I had to 
keep re-covering the exposed parts (perhaps I didn't have enough mulch 
on top to begin with).

I've also /heard /that termites love cardboard, and so that will attract 
them. I don't know what to think about that. I guess I wonder why that 
would be any different than wood chips, or just bits of bark or twigs. 
But I really don't know. That's just what I've read.

Here, the cardboard only lasted a year (less than that, probably). I 
don't know about termites, but the earthworms loved it! And it did a 
good job of killing grass which was hard to completely smother with 
mulch alone.
