Make it easy for yourself. Be clear on what you bring to the table and what you have yet to develop.
You have some very specific experiences that make you a valuable contributor. Do enough thinking, talking to someone who knows you, writing your list of accomplishments (real things; not puffery) and then use these as your filter to understand where you fit.
Doesn't mean you won't be learning new things and having new experiences. (For most of my career I defined that equation as growth and used it to measure the value of my current job.)
But the point is to know when to be aggressive with your opinions (based on your experience; and please express it that way) and when to listen, observe and learn.
The math here is to always be aggressive with your efforts; just know when you have something to say and when you don't. Check your experience list and you'll know.
