Pretty much anything that has good comparability with Linux.
I believe I remembered this netgear adapter working well for WiFi ap mode https://www.amazon.com/NETGEAR-Nighthawk-Adapter-Tri-Band-Wireless/dp/B0B94R78N7 but I have yet to try it myself

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

WiFi adapter as in a receiver (which you want to instead use to broadcast)?
Or do you mean a WiFi router?
If the former, this seems reasonably recommended based on a cursory search
https://www.tp-link.com/uk/home-networking/computer-accessory/ue300/
https://forum.openwrt.org/t/best-usb-wifi-dongle-for-raspberry-pi-4b/160103
but I can’t see this specifically as a supported device. It might mean you will need to run OpenWRT as the OS and use the dongle as the wifi part?
I mean PCI-E adapter for Wi-Fi broadcasting. Our can I use any adapter with OpenWRT?
Gotcha. So heres how to run it in QEMU (apologies if you know this bit already)
https://openwrt.org/docs/guide-user/virtualization/qemu
However I am struggling to find documentation on supported PCIE cards.
https://wikidevi.wi-cat.ru/List_of_OpenWrt_firmware_supported_devices
When I have read a few forum topics it seems like as long as there is a linux drivers available, and you can pass the wifi card from host to guest OWRT it should work?
Specifically I think you will need to look for an adapter which supports changing the mode it runs in, from receiver to Access Point (AP)
As I know every laptop Wi-Fi module support AP, so I think PCI-E cards should too
Couldn’t comment on whether all are supported, best of luck though!
edit - this isnt sarcastic - truly I hope it does work for you!
