This reply is not intended as an answer, but if you find yourself wanting to simplify more 'involved' menu choices, look into whatever is the cheapest Harmony remote. They work quite well with the Apple TV 4/4K, and allows creating sequences of multiple actions that can be applied to a single button.
Many remotes have macro capability. Problem is: Toggling CC on/off is a variable sequence, depending upon whether it's live or recorded.
I simply created two sequences and mapped them to two of the generic buttons on my remote. Again, it's not an answer to your original request, but a decent work around to the base problem of it requiring too many manual swipes and clicks on the Apple remote.
I like the idea suggested by Macnbaish. I toggle CC a dozen times a day depending on the content or how loud my kids are around me!

I had made a request for a command in the API to Enable/Disable CC. It would be nice to be able to get to this setting a little easier. Thanks!
How do u even enable CC on Android tv. I have Nvidia Shield.
There is no options menu while playing back to toggle CC on.
I see the CC icon, in each program description, but cant find away to enable them.
Edit. sorry... i didnt see this in the APple tv section...it just waht came up on search.
I have tried the native Captions option in the settings on Shield, but they have never shown up anywehre or in any app.
Press Menu (or Down) to open the Quick Guide. Navigate Up to select the tab headers up top for Language options. Press Right to select the Language tab, and there you will find Closed Captions and secondary audio options.

Ah thank u. did not see those tabbed options.
Agreed, I would love a faster way to toggle on/off CC.
(I tried the "shake remote" thing but that mutes the audio too, and it really does chew up the battery life, much quicker than the feature is worth.)
I would love a shortcut or button or IR/CEC command or whatever.
In the latest version we now have an /api/toggle_cc in the Channels API.
If your HDMI-CEC Remote has a captions button that may also work.
Interesting, thanks. Doesn't work on my Samsung, so I'm using a hubless Harmony remote. It doesn't have a captions button. I guess my only hope was that one of the newly supported colored buttons could be mapped to this command?
Being able to assign toggle CC to a colored button would be awesome.

The colored buttons are for navigation, so I'm not sure we want to go that direction.
Maybe we can add 'm' for mute and 'c' for captions? Then you can map those on harmony using Windows Computer.

I've also requested that Harmony add the native captions command into their available set of codes: https://support.logi.com/hc/en-us/community/posts/360048913534/comments/360012582353
Since my bedroom TV (where I use mute and closed captions most) has an IR remote, I was bummed by this answer back in August, but of course, understood your rationale. I hadn't returned to the Remote Shortcuts section in Settings since then.
Today I scrolled all the way down, to happily discover additional commands have been added. I now see that "Toggle Picture in Picture" in the list of options, which is totally awesome! Thank you, this is a huge jump forward in usability. 
It works beautifully. Perhaps you can consider adding "Toggle Closed Captions" below that too now, for the benefit of folks who don't have a hub-based Harmony, and are still happily using an IR/CEC remote? This would be a great feature for lots of Closed Caption users out there. For me, it would mean the difference between one button press, and eight (!), simply to toggle CC.
Thanks for the consideration, @tmm1.

Thanks again for this, it working great.
Can the matching setting be added to the DVR Clients page in WebUI?
I'm seeing odd behavior with this while watching recordings. When I set a button to be "toggle captions", and press it while captions are turned on (from the pull-down panel), all the button seems to do is dismiss the current caption. The next phrase from the next speaker resumes displaying captions.
This is when using one of the color buttons on my TV remote (LG TV), controlling the AppleTV app via HDMI-CEC through an amp (Denon).
Other controls on the TV remote seem to work fine (menu navigation, play/pause, etc.), even other color button assignments.

Ive seen the same or similar behavior with the cc toggle shortcut using the color buttons and HDMI-CEC. I gave up on using my remote for this and now use my apple watch with a shortcut using the channels API.
I did a lot of narrowing this down a few years back and gave up. See the thread below and read until the very end. It looked like it was solved at one point but it appeared again. At about that time got an apple watch and now have a shortcut on the watch face that does the cc toggle.
It looks like at one point @tmm1 had narrowed the trouble to what appeared to be two back to back toggles which can in some cases (like you and me are seeing) can confuse the software.
