Even without connections and with no data stored on it, my aurora serverless v2 mysql instances are hitting 90%, sometimes 98% of cpu usage. This is something that doesn't sounds good to me. Is this okay?

0.5 ACU translates to 1GB of RAM and 1 vCPU. That's very limited resources, inside of an RDS box you have other processes running beyond the engine, that's why you are seeing almost all resources being consumed. AWS doesn't recommend a configuration of min and max ACU = 0.5.
"The maximum capacity must be higher than 0.5 ACUs. You can set the minimum and maximum capacity to be the same in most cases. However, you can't specify 0.5 for both the minimum and maximum. Use a value of 1 or higher for the maximum capacity."
