choke choice for Turkey

[Mako19]

My father in law is bringing me turkey hunting this weekend and it will be my first turkey hunt.
I shoot a 12 gauge browning but have used it only for duck, dove, and skeet.

What choke do you guys prefer when huting turkey?
Also, what shells do you recommend?

Any other recommendations on what gear I will need or should bring?

Thanks in advance. Hope to post a good report Sunday.
