You can go for any WiFi card that uses an Intel WiFi chipset pretty much. Good cheap chipsets include the Intel AX200/201 which supports WiFi 6, and Intel AX210/211 which supports WiFi 6E. They also integrate Bluetooth within the chipset itself, so any WiFi cards using these chipsets will also have Bluetooth (check the product description to be sure). Intel WiFi chipsets also have great driver support and compatibility.
Just make sure your motherboard has a M.2 Key-E slot, which is the most commonly used interface on most cheap WiFi "cards", or you can get something that is in a more traditional PCIe card form factor.
Many AX200 WiFi cards cost around $20, which is a bargain considering what it offers.
