Canonical Sith Abilities (From Movies Only)
I decided to make a list of all the Force powers the Sith demonstrate in the movies. Feel free to let me know if I missed any!
Original Trilogy
------------------------
Force Choke -- Darth Vader
Force Choke over Zoom -- Again Darth Vader
Force Block -- Sorry, Han, your blaster isn't going to take out Darth Vader. Nice try, though.
Force Grab -- Han gets his blaster stolen by Darth Vader
Force Lightning -- Emperor Palpatine
Prequels
----------------
Corkscrew flip -- "I am the Senate!" Not sure this has much utility beyond looking cool, but I don't think he was able to do that from acrobatics skill alone.
Force Scream -- Done during the corkscrew flip. Not sure what its for besides sounding intimidating, but that's probably enough excuse to expend Force power on something for a Sith.
Sequels
-------------
I'm not counting anything Kylo Ren or Snoke did, since I don't consider any of them Sith, though they also demonstate some unique abilities, most notably the Force freeze of the blaster bolt.
I'm also not sure how to characterize the source of the teleportation connection regarding Kylo Ren and Rey, but since it's between two non-Sith, I don't consider that a Sith Force ability, either. That ability also seems to be unconsciously invoked rather than intentionally controlled.
Force Resurrection -- unclear how it works exactly, but somehow Palpatine returned, and I don't think that happens after being slam-dunked down a Death Star shaft without some weird wizard magic.
