The Pi Pico is intended to be the module format (and can be delivered on reels and used with some PnP machines), though it is much larger than it needs to be for this purpose (and this might be why you didn't mention it).
I have only implement touch buttons for hobby projects using a different MCU, but is there a reason to not just use the PIOs for touch sensing?
