Final input from me on this topic. The surprising, to everyone, result from the research paper referenced in the eevblog -
https://www.eevblog.com/forum/metrology/long-term-stability-of-temperature-sensors/?action=dlattach;attach=412153 Was that the cheapest thermistor had a drift of less than 0.5mK/year. It is the Murata NCP15XH103D03RC and is available from Mouser for 41c. Create a cluster of these and you have your low-drift reference.
