Just in lightsabers, the Hero takes it. Assuming, like traditional Jedi and not MMO characters, he keeps the lightsaber he made on Tython up until and past his fight with the Emperor - he would become very comfortable with using it.
I never played the Jedi story but if it is like the Sith stories at all, many sword and lightsaber wielding enemies would have fallen before the Jedi. He would have seen many fighting styles and maybe ways of fighting. Ventress is skilled but her style of combat would be just another style seen by the Jedi from his other Dark Side foes. He would counter, adapt and conquer the Sith Acolyte.
I posted the video because it was more fun than just writing "Canary Cry". She is the best fighter on the list below Batman and could beat Shang-Chi in that alone. The "Cry" would make Shang stop anyone as you put her on the list as the only meta-human.
Considering you are giving Shang no breaks, it would be a miracle if he gets to Canary without any broken bones. She would just end the tired martial artist.
