We are in the process of removing a rock bed from in front of our house (along the patio). We are digging this up and the old weed barrier that was there (from previous owners). Once all of this is removed, the trench is about 6-7 inches deep. If I plan on adding flowers and plants to this bed and topping off with a new rock or mulch, how deep should I keep the trench? Should I fill it back to being level with the lawn with dirt and compost? Or should the rock or mulch be a few inches deep?

I would refill the trench with fresh dirt and compost, leaving about an inch or two for the addition of any rock or mulch after planting.
