Sean,
Hearty congrats on your accomplishment. I have no doubt that it is well deserved and that you are a most worthy recipient. To attain such a position of responsibility requires a considerable amount of dedication, perserverence, finance, maturity, skill and a little humility.
Now, that is what the position requires. As we are all aware, there are those in such a position who don't necessarily have all the above in appropriate proportions.
My own humble opinion of what makes a good Captain is based on dealing with many good and a few bad for over 30 years.
Treat all those around you with at least the same level of respect you would hope to receive.
You already have everything else you need to be a Captain.
Believe it or not, it is that easy.
Congrats and well done again.
