An alternate view. As a child I had a very gentle mother. I sometimes threw temper tantrums or acted up at home. Like the OP her attitude was to talk to me and move on once I understood I'd done something that upset her (usually getting upset myself because I loved her so much and hated her thinking badly of me).
I didn't view her as a peer but I definitely had a relationship with her that was closer to that of a peer than my friends.
I didn't misbehave for others or in school not because I knew I wouldn't get away with it but because I was scared of them and the strange arbitrary (to me as a child) punishments they handed out.
I sometimes acted out at home because I felt safe or was trying to assert myself or test boundaries but never because I wanted to be bad or didn't care I was causing hurt or upset. Realising I'd crossed that line and how bad I felt WAS a punishment to me.
People sometimes used to misinterpret my behaviour to my mother as rude when it wasn't - in the 80s just talking to a parent like another human was apparently letting me run riot. People especially disliked the fact my mother would listen to my point of view and sometimes change her mind if she felt I had a valid point (granted I was older than 5 at that point).
She was definitely told I'd grow up to be an awful teenager. Didn't happen. I was quiet and studious and respectful. By that point I didn't act out with my mother either.
Maybe your kid is boisterous and loud at home because it's safe.
If you're not happy with the situation then absolutely change it - I'm not here you brand consequence-based punishment as evil and mean.
But doing it out of an arbitrary fear she might be a certain type of teenager or because all children objectively need a certain type of parenting seems silly.
I always figured teaching them not to be rude was about making sure, from a social perspective, they weren't disasvantaged by being rude shits and making people hate them, and from an emotional perspective ensuring they don't discount others feelings and act without empathy.
The child OP describes is not ruining others' days and seems very empathetic. I think if OP's happy with their relationship then changing it on the advice of internet strangers based on assumptions about her development and personality is unnecessary.
