The Lone Wolf and Cub series for sure. Maybe start the traditional way with the “americanized” “compilation” Shogun Assassin.
On the modern side, rza’s Man With The Iron Fist is worthwhile, along with the Kill Bills.
There is a lot of overlap with kung fu. I would recommend 36 chambers of Shaolin as a good entry point there.
Fresh (1994)
Pump up the volume (1990)
