I can only speak for the Smabat ST-10, there is actually another NiceHCK cable with better conductivity than the ones you have listed. It is number 053 in hakuzen's list, I have the mixed copper/silver version and it adds a warm tilt to the ST-10 which I like.
I would ignore the TRN 8-core cable, read HERE for the reasons.
If you want to stay with the neutral character of the ST-10, then I like to use this SPC cable from Penonaudio.

I also felt that the amount of medium and high sound of Smabat ST-10 was a little short with the stock cable, so I changed to the silver-plated MMCX cable to achieve satisfactory sound balance. (It is a cheap cable of only $ 15.)
Silver-plated MMCX cables are highly recommended for those who have Smabat ST-10.
