There is an old discussion on Weeds back in 2009. This is a reply to that discussion, that seems appropriate to me.

I'm not pro weed at all and I don't subscribe to natural succession in the vegetable garden.
There are many plants that can be deployed to cover the soil. Many unfortunately aren't perennial. But I'm sure there is a botanical niche on offer for every backyard address. You just have to find it.
I think ground cover live mulching is the ultimate companion planting system.
I should add that the perspective I'm working on includes Vetiver Grass both as a source of dry mulch and as a in bed soil enhancer.
Vetiver is the ultimate soil enhancer but it isn't a 'ground cover'.
Exactly Dave, Vetiver is a good plant for many of us to utilise.
We have noticed that we have a few termites under some old logs in the back, if we had chooks we wouldn't have that problem so we have spread some teatree mulch over the bare ground and near these prone spots and hopefully when it rains the water from that mulch will deter them. I could have easily used some teatree oil from the melaleuca tree, in water and have a similar effect on the termites.
As we are getting older, we don't want to be pulling out weeds, so dry mulch works for us. I know green mulch may work better, and we have done that when we were younger. The dry TT mulch is mainly used in the pathways through the garden.
Chop and drop and using the mulcher allows that green stuff to go back to the plants.
One thing I have noticed is that we don't seem to rely on our big aerobin for mulch. It works well but as hubby is the worker/feeder in the yard we don't seem to get the ratio of green to dry brown stuff right.
So to summarise, we use dry mulch rather than living mulch to keep us going at this stage. For a younger gardener, I would highly recommend using any green living mulch.
