Phone: S24 Ultra 256GB, Carrier: Verizon, Problem: Charging cable only works one way, nothing happens when the cable is flipped, charging speed is extremely slow, Wireless charging works, but wireless charging has always been slow in comparison to wired charging.

I've enabled fast charging, I've cleaned the port, no liquid exposure, I've read multiple forums and concluded the PCA board (sim card and charging port) needs replacement. I've tried 5 PCA boards, from 3 vendors. The boards fixed fast charging. Problem: the phone WILL NOT connect to the Verizon network, I've brought it to Verizon, they've reset network connections, installed a physical SIM card no changes. eSIM or SIM, the phone can send and receive texts, calls: phone will ring, but if either person answers the call, the phone drops the call. I believe the PCA board needs to be programmed to work on the Verizon network. I've seen videos online of people replacing the PCA board and the phone works.  My Verizon tech says she has never seen a Galaxy S24 work successfully and connect to the network once replaced.  Is there such a thing as there being a Carrier specific PCA Board?

@Members_86N26GE This is indicative of a damaged charging cable or an inexpensive (cheap) cable which only has wiring to support the very basic low speed charging. 

I recommend that you get a quality cable from Samsung or another reputable source and give charging a try.

Good catch, I forgot to mention that I've bought 4 new 240W cables, tried my girlfriends iPhone USB-c cable and brick, my existing USB-c cables and 3 charging bricks, my steam deck 100W brick and cable and my PC USB-c ports, same result with the cable only working one way and slow charging.

Unfortunately that means that, the most likely cause is a damaged USB port on your S25 Ultra.

Galaxy S24 Ultra, I believe so, but none of the 5 PCA boards worked. The original board was placed back into the phone and the phone connects but the original problem persists, slow charging. Thank you for your responses and offering to help.
