Option to add external antenas through the dongle RP-TNC/SMA connector that are directional like the classic Cantenna or omni if you dont know where your target(s) is/are physically placed.It's not only about the manufacturer, but the chip that matters most. Here, you have a document that displays what are the best and more capable(with more features) USB devices for wireless monitoring. You dont have to install drivers on Windows, since you will present this dongle using usb-passthrough. Because those USB dongles have better plug-and-play support on Linux.

This video is a good example on how to passthrough a USB card to a Kali Linux guest inside VirtualBox. This way, it will work like a card being plugged directly to the vm. Since a Virtual Machine is doomed to use the hypervisor infrastructure to create network cards, depending on how this is managed, could break monitor mode and other capabilities related to pentesting.

Allow the dongle to be accessed using usb-passthrough.

It's easier to chose hardware if you have a wireless card that can be removed without having to teardown your computer/notebook.

Monitor Mode support, or other features like this card that supports packet injection.

Some of the reasons that would explain the limitations of using your built-in wifi adapter instead of a USB dongle on a pentesting focused vm:
