It could also help to shift the soil to something more fungal (and acidic) which is not so much preferred by weeds. Some raspberries can thrive in ordinary soils though, even amongst the weeds.
Hypothetical but maybe introducing some saprophytic, soil/wood-dwelling fungi like stropharia could help? I know they killed off my garlic mustard where I put them.
I strongly recommend against ground cover fabric, which can become a place where weeds sprout up through the fabric and become embedded into it, making it impossible to weed.
