I was told there is a hub that can provide both gigabit ethernet and the use of a wired headphone, for the new iPADs (released October 2018).
Here's what the company said:
Why not get this instead and be done with all the dongles and adapters? It has gigabit ethernet, 3.5mm headphone jack, power delivery pass-through charging and 8 other ports!

From the looks of it it seems cumbersome... but it would solve my complaint about wanting to use a gigabit ethernet USB-C adapter and Apple's USB-C to 3.5 mm Headphone Jack Adapter.
However there are reports of wi-fi issues at least with Apple's USB-C to 3.5 mm Headphone Jack Adapter, and one user said it's draining too much battery:

Look into these threads for further info. Since this has been reported (at least the wi-fi problem) by multiple users I think it would be wise to get the headphone adapter from another brand.
I have no idea if this hub would work with the new iPADs, yet no reason why it shouldn't.
And about the previous iPADs/iPhones not using USB-C, but lightning port instead, I discovered something interesting today:
I left my iPAD Pro 10.5 (256 GB, wifi+cell) with the non-gigabit combo:
- The Belkin USB 2.0 Ethernet Adapter (F4U047bt). It can be seen here:

- The Lightning to USB Camera Adapter from Apple:

They are both connected to a CAT-6 ethernet cable, and the router is also gigabit. And the iPAD doesn't have wi-fi, bluetooth or cellular data on. Airplane mode is disabled to avoid iOS warnings.
Well, here's the thing: I left my house at 9, 10 AM... the iPAD was fully charged or at least close to 100%. When I returned 4 or 5 PM it was down to 50%.
I also leave the iPAD with these settings:
- Auto sleep after 15 minutes
- Wake and sleep when the Smart Cover is open/closed.
I didn't left the iPAD doing anything. So that means it will continue to drain battery if we leave ethernet plugged. It doesn't need to be used, the mere fact it was plugged to the lightning port was enough to drain the iPAD's battery.
Of course that is not an issue with the gigabit "combo", since it will also charge the iPAD.
Since this is the case with these adapters I also wonder if with the new iPADs and any gigabit ethernet adapter it would behave the same. As you can see from the graph the battery was reduced to 50% without any use at all. So it was really the ethernet adapters that did this.
