IMHO, on a snap throw to first after the pitch unless your 1B is really athletic and moving on the pitch it is almost impossible to get back and straddle 1B and look to receive the throw unless your catcher doesn't have an arm; which then she probably shouldn't be throwing down anyway. The sweep tag method is more a pick off move to keep the runner from getting that huge lead on release. If she gets too far off the bag the catcher runs at her and makes her choose.
The straddle the bag option I'd imagine is more used in baseball when 1B plays behind the runner and can move up to the bag.
