For the PATA to SATA adapters, they exist to the extent the SSD supports
them. Smart here is not standardized... but smartmontools has a big enough
database to keep you happy...

Interesting... I have several SSDs in the field now that have been powered
on for 7 or 8 years... I've not yet seen this behavior, though I do see a
few of them die every month due to old age....

Yes. "Only as good as the card you put in." and most of the cards are poo.
Though the latter-day CF cards tend to be quite good since they are for
high end cameras and tend to use relatively good quality NAND to get the
performance those cameras need, endurance goes along for the ride. Most of
the issues with CF and SD cards are in continuous use, though, where
there's lots of writes and not much idle time for the card to do anything
about it and power failures are a lot more common on CF/SD cards with high
write loads than for SSDs...
