>The conclusions are as follows: the original daily temperatures
(mean temperature, maximum temperature, and minimum temperature) can be well
reproduced by ERA5 reanalysis over China. ERA5 tends to exhibit more misdetection
for the duration of extreme temperature events than extreme temperature intensity and
frequency. In addition, ERA5 performed best in the summer and worst in the winter
> Comparing ERA5 with the other two datasets, ERA5 temperature presents more extreme temperature and small outliers for regions southern of 40° latitude and less extreme temperatures in areas over the Black Sea. In Scandinavia, ERA5 temperatures are more frequently extreme than the observational ones
There are more articles like these on how well ERA5 captures temperature/wind speed/etc, or certain global events, extremes, anomalies, etc., in different locations and time, but I couldn't find more for your other questions (on mobile).

But even in Europe the dataset can have some issues, e.g. https://www.mdpi.com/2073-4441/14/4/543
