Internal (m.2) wifi card vs USB, what to get? Is it recommended to install dual boot w10/mojave on the same drive?

I'm trying to fix my yoga 730 iwl Hackintosh (i5 8265u, 8gb 2400 ddr4 ram, 2xtb3 ports, uhd620,256gb pm981 nvme and Intel 9260 wifi) like my 730 ikb (I had to send back due to issues and got this) and I was wondering on how to fix my wifi/bt, the laptop has an intel wifi/bt5 9260 that I like for use in windows due to bt 5 and its pretty good range/speed, is there a comparable card compatible with osx? If not is it better for me to get an internal m.2 one or an USB dongle? Is it possible/advisable to install both oses on a single nvme drive (not necessarily this 256, might upgrade to 512 or 1tb if needed later on)? My laptop only has a single m.2 slot for storage unfortunately :v
