Turris MOX modules question

I’m interested to order two MOXes but I need to confirm following:
Functions I want:

  • POE
  • 5GHz Wi-Fi (2GHz is not mandatory)
  • Ethernet ports

What modules / upgrades do I need? I see following options:

  1. A (+POE upgrade), B, C --> what 2GHz and 5Ghz Wi-Fi cards are included?
  2. A (+POE upgrade + Wi-Fi upgrade), C --> what Wi-Fi card is included? Is it exchangeable card or chip soldered on board?

Thank you…
