I am planning on killing my lawn and filling the area with raised beds with gravel in between the beds. I will be using the sheet mulching strategy to kill the grass. I’ve used this strategy successfully to prep for my existing beds. My question is this: should I put a layer of anti weed tarp before installing the gravel, or should the sheet mulching do enough to prevent weeds?

Tarp is plastic and will break down over time. For that reason alone I’d never use it.
