The extension cable is only 3 ft. It may be good for car use or something. But I feel a 6-footer would be more optimal/versatile for desk/office use.
Both the splitter and the extension cable are 3-pole cables. So they will only work for headphones (listen-only mode) and not for headsets with mics (listen and talk). Count the number of metal segments on your hadphone's plug (which are separated by colored plastic). If it's 3, you are good. If it's four, don't buy.
- HDMI with 4k at minimum of 60Hz
- Ethernet
These are the two areas manufacturers typically skimp

USB-C supports something called alternate mode. The computer and USB-C device can negotiate and agree to send non-USB signals over the USB-C cable's data wires. Both the USB-C device and USB-C port on the computer have to support the desired alternate mode. Common ones include HDMI, Displayport, and PCIe (Thunderbolt).
A vanilla USB-C port does not support any alternate modes. All they can do is power and USB data.
HDMI alternate mode gives you HDMI-out, but I don't believe it supports HDMI + USB data. HDMI does support something called HEC - HDMI Ethernet channel. But it's limited to 100 Mbps Ethernet. (It also supports ARC - audio return channel, but you're probably not interested in that in a dongle.) Resolution and refresh rate Depends on HDMI version. HDMI 1.3-1.4 (by far the most common) maxes out at 4k@30 Hz. HDMI 2.0 gets you 4k@60 Hz.
HDMI + Ethernet is usually done via HEC - HDMI Ethernet Channel. Unfortunately it's limited to 100 Mbps.
HDMI + Gigabit Ethernet usually requires the USB-C port support Thunderbolt. That raises the price substantially. It may be possible to do it using Displayport (see below), but I can't say for sure.
Displayport's USB-C alternate mode is a lot more thorough [displayport.org]. It includes enough bandwidth for 8k @ 60 Hz (usually split between multiple monitors), 5 Gbps USB data, backwards compatibility with HDMI (basically converts the Displayport signal to HDMI), and a few other goodies.
It does not support Ethernet natively. But its USB channel has enough bandwidth for Ethernet so it could be implemented as a separate USB-to-Ethernet adapter in the same box. I should mention however that I've seen signal interference when USB 3.x and USB-to-Ethernet are close to each other. The Gigabit Ethernet USB-c adapter I bought drops to about 200 Mbps max if I'm copying files over a nearby USB port.
The cleanest way to do all this is probably via Thunderbolt. Since that's just PCIe over USB-C, you can build just about anything on top of it. But as mentioned, the chipset increases the price considerably.
Unfortunately in an attempt to "keep things simple" for users, these requirements of the computer's USB-C port are usually omitted in the product description. If you dig through the UGREEN hub's Q&A section (under Compatibility), you'll see that this one requires your USB-C port support Displayport alternate mode.

i vaguely recall vga/dvi to usb adapters being a thing, but i guess the bandwidth and whatnot got more complicated, also with these being hubs that are a lot more than just more type a ports
