Are monarchies like Kuwait authoritarian, autocratic, constitutional monarchies, or mixed political systems?

I am trying to find a clear conceptual difference in terms of how different monarchies are defined or classified. For example, let's consider three countries with monarchies: Kuwait, UAE, and Norway. How would we classify each monarchy and why?

I think it's clear to me that the UAE is an autocratic monarchy, however, I am confused in terms of the difference between Kuwait and Norway, given that both have elected representatives, but in the former the royal family still maintains greater political power, does that make Kuwait autocratic as the power is concentrated within a small number of individuals or a mixed political systems where elections are allowed and representation exists, but the monarchy still retains legal power over the parliament.
