You can definitely get stable 1gig throughput through WiFi. Doesn’t even need WiFi 7/6E - possible on 6. Ran a WiFi bridge like that for years and - no packet loss, consistent gig through and maybe +1ms latency

The gotcha is both ends needs to be good radios. So a router to router bridge tends to work better than router to end user device. Also had near LoS which presumably helped a ton
