I personally would use joint compound in a mud pan thinned out with a little water but who am I to argue with Tom Silva. Anyway, any of these methods will work for you. One thing you may run into is if you have a texture on the wall you’ll have to match it after your patch is nice and flat. For that, there are spray textures in cans that you can buy at Home Depot which will work as long as it’s not a knock-down or skip trowel texture. For those, you will need a lot of practice, a drywall guy or a wider range of acceptability.
