Keep it simple, 3ft or 4ft snood (hook length) with around a size 2/0 hook.
This type of rig would do and you wouldn’t need to clip it down for a short cast.

3oz or 4oz plain or grip lead.
2 or three Lugworm or a large Ragworm on the hook for bait and chuck it into the surf, somewhere between 30 and 60 yards out, keep away from the surfers.
You can also use Mackerel or sand eel for bait.
You will have more fun with a Bass or Carp rod, than a beachcaster.
Best to hold the rod and keep in contact with the weight, but use a rest if you prefer.
Evenings or early mornings may be the most productive, possibly on a flooding tide, bringing the fish in looking for food.
If you want to try and be clever, take a spade and turn patches of sand over in front of an advancing tide, this can act a bit like ground baiting.
