I think longevity is related to the technology SLC versus TLC or QLC along with how many cells are reserved for wear levelling and how many erase cycles have been performed.I quote from How-To-Geek :
"Larger capacity SSDs, due to having more available sectors and more "room" to use before failing, should last longer in a predictable manner. For example, if a 250GB Samsung 840 MLC drive failed at 900 TBW, it would be reasonable to expect a 1TB drive to last for considerably longer, if not necessarily all the way to a massive 3.6 petabytes written."

So this would be a good point to get a 1TB drive instead of say a 256GB even if the need is not for that kind of capacity.
According to Scratchy the main concern with a Pi is not wear from use but how long you can store it on the shelf unpowered before cell leakage leads to memory loss. Apparently ambient temperature makes a big difference.
The kitten named Purr recommends storing your raspberry pie in the refrigerator with the whipping cream. I'm not sure about that.
Personally, I'd only get a larger drive if I needed the larger capacity. Reliability is determined by too many other factors than size.
