Good push pull pots don't exist. You get rebranded ones from Dimarzio or PRS if you wanna pay extra, but they're all the same, cheap build, I think Alpha makes them. They have smaller post diameters than CTS.
I would not use them on Volume positions, only on Tone if it has to be.
For caps, I like paper and oil ones. I bought some recently priced NOS types of ebay and they give the woman tone, quite impressive actually, like a Wah a bit. You can buy that kind of stuff here at BKP, too.
