Fresh Ventura Install - Is USBInjectAll Still needed? How about Skylake to KabyLake spoof?

Hi, I have working Catalina system with GA Z170X UD5, i7-6700k, Radeon RX480. I don't have windows on any of the drives. I am trying to create Open Core installer from the Catalina system and then install Ventura to a new NVMe M.2 SSD drive.

I am following https://dortania.github.io/OpenCore-Install-Guide.

So far my EFI looks like

Some questions:

1. I have Archer T4U V3.2 USB - this is what I use for wifi on Catalina. Will this ever work in Ventura?
2. I also have Fenzi T919 - this is PCI wifi card that I am not using but would like to use if I can't get the USB wifi card to work. Any tips here? The above linked guide doesn't seem to suggest I need anything.
3. Regarding my RX480. As I understand this should work without kexts or anything, provided I have the lilu and whatevergreen kexts. But now on to the skylake-Kabylake spoof question...
4. Spoofing SkyLake to KabyLake. What does this amount to? Just specifying 18.3 as system in symbios? Or is there something else to add in config.plist, or a boot arg or something? I just want to make sure the iGPU is available for use if needed.
5. USB mapping: wow there is so much info on this. Really not clear what I should do. In hackintool I see attached. USB works fine on this Catalina system and just not sure if I need to do anything regarding USB. When I read the info about USBToolBox it seems to suggest that you do the mapping from windows. I don't have windows. So am trying to figure out what I should be doing, and whether I need to use USBInjectAll.

Anyway, hoping for some pointers on these nuances.

thanks
