Really?
Digital has precision, not necessarily accuracy. There could be an entire discussion of double and triple precision data logging here
On the other hand analog thermistors have incredible precision, but less so on accuracy.
The calculation of wire resistances with temperature changes in a home environment are incredibly tiny.
For me a 10K thermistor, a bit of code (or analog device) to change the non-linear temp response, is an easy one to buy into.
But I certainly do admire your learning about data logging and instrumentation!
