You can parallel as many caps as you want, for more capacity and

Utter nonsense.

Why do you think they make caps with a voltage rating ?

I was worried about spikes and transients, like the Evox Rifa article
warns about.

You won't see any spikes on a PSU reservoir cap. It would require a transient
with a huge energy to do that.

I suspect you've misread or misunderstood the app note. What page are you
referring to ?
