XPS 8940, add 2nd LAN PCIe 10/100/1000 ethernet card

I have a Dell XPS 8940 on order. I intend to use this PC for control/monitoring of my home security system. I will need to add a 2nd isolated LAN (additional ethernet interface). This additional ethernet port will be connected externally to a POE ethernet switch for use with my security cameras. What is the recommended PCIe 10/100/1000 ethernet card for this purpose?

Wouldn't any PCIe Ethernet card be suitable for this purpose? Perhaps this Dell Ethernet card will work: https://www.dell.com/en-us/shop/tp-link-tg-3468-pcie-network-adapter-gigabit-ethernet/apd/a9008619/networking#support_section

And there's always a USB3>Ethernet dongle...

PCI-E ethernet is NOT recommended for many reasons.

If you need an additional port you do that via USB2

The specific model is recommended because most OS recognize this without needing to install drivers.

Its plug and play.

The only advantage of a USB Ethernet adapter is convenience. For many reasons, a PCIe Ethernet card is better: https://superuser.com/questions/294017/what-difference-does-it-make-whether-the-computer-uses-usb-ethernet-adapter-or

If you have reasons to not recommending a PCIe Ethernet card please cite them.

Yes, I am definitely looking for a PCIe 10/100/1000 ethernet card. This will need to handle multiple 4K / 8 MP / 60 Hz ONVID video streams. I definitely don't want to be throttled by USB2 max speed of 480 Mbps and other USB overhead issues. I suppose a USB3 to Ethernet adapter might do the job but I expect the PCIe interface would facilitate the highest performance (16 G transfers/sec) with the least bottleneck. 

So speedstep are there are other reasons to go with USB vs. PCIe (other than convenience) ?

The TP-LINK TG-3468 PCIe Ethernet card Vic384 linked-to would probably do the job just fine. The only reservation I had against it and other 10/100/1000 Ethernet cards I found on amazon & Newegg was that most of them are 10+ year-old designs and I was skeptical about the actual PCIe throughput (all were PCIe 1.0) and the level of Windows-10 support.

After looking a little further I discovered that there are a number of newer PCIe cards that support 10/100/1000/2.5G (quad speed) Ethernet. For example, this card is a much newer design and supports PCIe 2.1 :
