It depends on what you want to replace the weeds with. If you just have bare soil then weed seeds will germinate and you'll have weeds again.
If you really don't want to do the dig and plant and weed thing, I'd suggest that you just mow the borders, right up to the fence and around the shrubby plants and let the lawn spread to the fence. You can pull the weeds out of the base of the shrubs a couple of times a year so that they don't get totally overwhelmed.
If you spray you'll just be left with dead plants which you'll have to dig/pull up, then you'll have bare soil and you'll have to decide what to do with it.
