I agree.
You don't learn or know C++ in the way you learn or know C.
You never have the total language spec in mind. Much of it you will never (and for some of it should never) come across.
The way I think of it
C is an abstraction of the machine, so thin it's nearly transparent.
C++ is an abstraction over programming paradigms, letting you pick how you think.
Everything else abstracts the machine away, replacing it with a VM, runtime, or model of its own.
The same way a good project has a clear model of the problem it should have a clear C++ pattern in use.

-Werror might help with that

Looks like someone fell for the C abstract machine trap yet again. No, C is isn’t an abstraction of the machine.
C Is Not a Low-level Language: Your computer is not a fast PDP-11.

As a corollary, all processors are C VMs, anyway.
It may not be an abstraction of a real machine. But the C abstract machine is very close to the foundational idea of how a computer work. And it’s quite easy to bootstrap.
Importantly my work involves me often being able to look at C and think about the assembly and back and I regularly work on ESP32, ch42(riscv) and atmega avr8.
I couldn't do that with mciropython on any platform.
C is a thin abstraction, python isn't.
