Yes, this is what I want to include - the cost metric. Although it will be tricky for systems with consumption-based pricing: BigQuery and Athena. And Snowflake has almost consumption based pricing - while you pay for warehouse time, it can quickly spin it up and down based on load. Maybe use some assumption like - the price for running queries on consumption based systems is equalized to one hour of run time of other systems...
