I think your front 02 sensor is bad, its cycling from full lean 20 afr to full rich 11 afr. With no throttle input. Commanded afr is steady at 14.7, and fuel quantity delivered from port and direct barely changes

Think I should just try swapping it out? Front one is the AFR sensor right? It's an expensive part to just try swapping. Any recommendations on one to buy?
I was worried about it since I left it sit out of the header for a bit when I was doing my swap. Do you think cleaning it is possible to avoid a full replacement?
I does seem strange to me that the AFR is consistent. It's fluctuating in a consistent manner.

Its spiking lean right when I get on the throttle then going rich right when it misfires and only when it misfires. The 3rd one didnt misfire, but I guess neither did the 5th and it had the same AFR readings and 1,2, and 4.
