How can one be an effective participant in leadership meetings?

As a senior IC, I am included as part of leadership meetings (Director+). I gain a lot of early insights into business direction, which is great. However I would like to see how i can take part in the discussions and have effective conversations?

I am looking for a book suggestion and/or framework to use on how to go about improving on this?

Few dimensions which could impact this -

1. Personality of the individual
2. Awareness/one’s expertise of the topic being discussed
