The average temperature of the universe today is approximately 2.73 K (−270.42 °C; −454.76 °F), based on measurements of cosmic microwave background radiation.

That's purely academic. IRL what actually matters is “how big and reflective is the thing you're in”.

Wonder how they calculated the "average" temperature. Was it weighted by mass or by volume?

Doesn't matter, it's just the eventual temperature of a black body kept in deep space

Only mass-weighting really makes sense here imo
