> and I think it is somewhat similar to say that you have to "lie a bit on your CV". [...] For context, I'm early in my career (3 YOE)

Please consider this input from my YOE battle scars:

1. Don't contradict your team while in a meeting with outsiders, but then you're obligated to follow up with your team offline, to try to mitigate any damage, and try to make sure it doesn't keep happening. For one example of why, I've seen one person consciously "mis-promise" things to customer, and when I talked with them offline about we couldn't be saying that, because it wasn't true, their response was "they won't remember". Narrator: "They did remember." And that's possibly why that person and a few others aren't very wealthy today.

2. Not everyone believes in "lie a bit on your CV" nor similar dishonesty. You'll probably meet colleagues, who you respect, who react to that with surprise and disappointment. You could also get fired for it, with cause. Especially if you're calling yourself an engineer, since determining and telling the truth is much of your job.

3. Though, on the other side of CV honesty, be careful about always using team-speak/think when in an interview context. Out of habit, you might naturally say "we" when talking about something you were instrumental in. But some people who think lots of people lie on their CV are going to hear that "we" as you generously including yourself in the accomplishments of others. I've started switching modes a little more for interviews, expressly claiming more credit, such as by saying unambiguously when I was the sole designer and implementer of something.
