5k KM is for severe usage. So it means you idle a lot or are driving the car in a hard o aggressive way. That’s what my manual says for my 2011 3. And that’s what I do. 5K Km changes because I wait a lot in idle because I live in a hot climate and need the AC on.

For example, when stopped and the transmission in drive, the transmission does not disengage, rather it wants to “go”.

My 2011 Mzd 3 does this as well, I always thought it was normal?. Isn’t?.

Yes
