I need 40uf~200uf, 350v or higher, which one of the above sounds better?

For those small values, you can go for a film capacitor, or an oil capacitor. I've had electrolytics in the output stage of single-ended amps and all of them sounded mediocre, even "audiophile" ones. Going to film was a huge improvement.

depends where in the circuit they're used... except for JJ, I wouldn't put those anywhere.

I am partial to the out of production stuff myself. BHC, Aerovox, Siemens, Epcos, Shizuki (older stuff), Cerafine, and Black Gate.

woops, forgot to mention it is for high voltage power supply of a SRM-1 (MK1). The room limitation pretty much prevents film caps from being used.

For power supplies, low ESR is the key to clean power. Those audiophile caps are designed for coupling stages. They do have low ESR but it's such a waste.

The consensus view seems to be that Panasonic TSHA / TSHB is the way to go for high voltage electrolytics. Many people will tell you that they are as good, or better, than Blackgates or Cerafines. I have also used JJs which are fine. I've not tried the others in your list as I generally try to design them out of the signal path.

One datapoint:

The 500V CDE caps have the same ESR as the 500V Panasonic TS caps, but the measurement is given at a higher test temperature. Same form factor as well.
