Remote desktop running on PC and quest over wifi using av1 @ 120 mbps generally always provides a superior experience to a link cable though wifi6 or better may be required but it won't hurt to test on something lower provided signal isn't an issue and even on WiFi6 you should have the PC wired to the router. It uses the encoder in a 4000 series GPU to do av1 but I think the 3000 series supports is as well and the dual encoders in a 3070 should be more than sufficient to handle transcoding the video with av1 and using 120 mbps makes sure image quality is uncompromised.
I've been using remote desktop since the Rift S or perhaps the original Rift.. it's hard to remember really but the main benefit even back then was oddly better performance in steam vr vs native oculus (meta uhg) software. I definitely used it with my Quest 2 starting immediately, I've had WiFi6e for years now and then when I got the quest 3 shortly after it launched I started using it on that and I've never had an issue despite my router being 20ish feet away and behind 2 walls... I have a high end pc though and a really high end router.
