I highly doubt that macOS fullscreen has that much higher latency than Windows fullscreen. The latency is so fine that I play Windows games over a capture card using OBS as the monitor. (The Mac has a 120Hz display though.)
I like to play games like ARC Raiders using that setup. Works perfectly fine. Sure it sucks that I need Windows at all for it, but SteamOS isn't an option yet due to my 3090
