Pace and shoes for first marathon?

Hi all, running my first marathon on November 19 (Philly). I have done all my long runs in the Hoka Clifton 9 (super cushioned) but I want something a little faster for race day. I ran a half marathon on September 23 in Saucony Endorphin Pro 2s (carbon plate) at a 6:40 pace, but other than that I haven’t worn them much. Should I run the marathon in those carbon plated, stiff shoes, or is that risking getting hurt during the race? Also, what pace should I be running the marathon at?
