Unfortunately, we can't answer this specifically as we don't have the experience. However, the question remains in the Community in case anyone can help.
I'm not completely sure of the answer, as the properties provided don't specify whether the cable is active or passive.
For a length of 3 m, it is common for Thunderbolt 4 cables to be active in order to guarantee 40 Gb/s transmission over this distance.
I advise you to check directly with the manufacturer for confirmation.
Thunderbolt 4 cables are generally compatible with Thunderbolt 3 ports, as they use the same USB-C connector and are backward compatible. Therefore, this Thunderbolt 4 cable should work with Thunderbolt 3 devices. However, it's always a good idea to check the specific device specifications for any additional requirements.
You can use the USB C - USB C cable (5 m, USB 4.0) from Onit as a link cable for your Meta Quest 3, as it provides the required USB-C connection and is of sufficient length. However, it is important to make sure that your PC supports a USB-C port with sufficient speed to utilise the full power of the cable. The Meta Quest 3 is compatible with USB-C cables that support a data transfer speed of at least 5 Gbps, which is the case with USB 4.0.
The cheaper (but "better") cable is currently on sale at Brack. Onit belongs to Competec, as well as Brack.ch. https://www.brack.ch/onit-usb4-kabel-premium-usb-c-usb-c-2-m-1538677

USB 4.0 is a standardised specification. It was announced by the USB Implementers Forum (USB-IF) and is based on the Thunderbolt 3 protocol, ensuring compatibility and consistency across devices that support this standard. The Onit USB4-Kabel Pro, with the product ID F01468, complies with this USB 4.0 standard, offering features such as high-speed data transfer and power delivery as defined by the USB-IF specifications.
