Oh, be nice, or would trial by combat be a better way
to settle the matter?

Unless you can point me
to a page that specifies an electrolytic capacitor for a run and/or
start capacitor for an AC motor.

Are these sufficient?

Note the lack of polarity markings.
Keltron Aluminium Electrolytic Motor Start capacitors
are manufactured...

From the Gainger catalog under Dayton:
https://www.grainger.com/category/capacitors/capacitors-and-accessories/motor-supplies/motors/ecatalog/N-19eb
These electrolytic, nonplarized capacitors are designed for
normal intermittent service on single-phase AC motor starting
circuits.
