--- Edit - I think I fixed it, update at the end of post ---
Here's the problem:
iTunes will not automatically launch when iPhone is connected.
iTunes will not reliably sync when iPhone is connected.
iTunes will not reliably see iPhone when it is connected.
iTunes will frequently stop syncing and iPhone will disappear from iTunes after syncing has begun.
iTunes will not reliably sync automatically over Wi-Fi despite this option being on.
Here are the steps I've taken:
Restarted the computer.
Restarted the iPhone.
Verified that Windows is recognizing a USB device is connected.
Removed all other USB devices, tried different USB cables, tried different USB ports, tried both the old USB2 cable and the USB-C cable.
Verified iTunesHelper is running.
Wiped and restored iPhone.
Wiped iPhone and did not restore.
Uninstalled iTunes using the normal uninstaller.
Uninstalled iTunes using Revo Uninstaller (to remove left over remnants the standard uninstaller leaves behind).
Followed the steps listed on Apple's "If your computer doesn't recognize your iPhone, iPad, or iPod" support page.
I've uninstalled and re-installed the drivers for the iPhone, either manually using "usbaapl64.inf" as per the support page or using the Apple Mobile Device Support from the iTunes.exe installer.
Multiple calls over several hours on the phone with Apple Support.
This has impacted a previous phone (iPhone 7 Plus) and my current iPhone (iPhone 12 Pro Max). The problem has existed for me across many versions of iOS to varying degrees. It used to be easier to work around, now I'm often unable to successfully sync at all. It was first noticed after iTunes removed the manual sync option on iOS which is how I would typically sync before. It has existed as a problem for me since that iOS update.
iTunes is up to date and is kept up to date with the current available version. I use the Windows 64bit installer directly from iTunes. I have tried the Windows 10 App Store version to see if it made a difference, it did not. I am currently using the stand-alone installer. Like with iOS this has been a problem with each version of iTunes since I first noticed the problem. Updating or reverting iTunes has not had much noticeable impact.
I've tried connecting to a laptop short of actually syncing the different library there, and it seems to function normally. By that I mean iTunes sees the device consistently and prompts me to sync it. This (and that it's happened on two different iPhones) leads me to believe it's a problem with the installation on my PC.
Some things I've noticed that might be part of the problem:
My Apple Mobile Device USB driver listings fall under "Universal Serial Bus devices" and Apple's support page implies they should be found under "Universal Serial Bus controllers".
The iPhone seems to be found by Windows and shows up as a device with "Internal Storage" in File Explorer.
The iPhone will always charge when connected to the PC. It seems like Windows can find the iPhone, but I'm suspicious it might be routing it as the wrong type of device.
After uninstalling iTunes and/or the iPhone drivers Windows will often install a driver update. The update is listed under "Driver Updates" and "Apple, Inc. - USBDevice - 486.0.0.0". It seems suspicious to me that I would need this as it installs after installing the latest version of iTunes and/or Apple Mobile Device Support.
I can occasionally (now very rarely) complete a sync successfully by doing the following. Restarting the PC and the iPhone. Launching iTunes. Connecting the iPhone. At this point it will either sync normally or start to sync and then disappear. If the sync fails and the device disappears the iPhone will not be found in iTunes again unless I repeat the series of restarts. If the sync completes successfully, and I try to sync the device again the sync will fail and the device will disappear again until I repeat the series of restarts. A complete uninstall/re-install of iTunes seems to allow me one successful sync/connection before the problem returns.
Any help would greatly appreciated. I've tried everything I can think of, and I'm pulling my hair out. The only thing I can think to try next is a complete re-install of Windows, but I'd like to avoid that if at all possible. I'd just like to know what's gone wrong.

I was bothered by the USB drivers showing up under the different heading of USB devices instead of USB controllers in Device Manger. There were two Apple USB listings under devices, so I manually attempted to "update" the driver from the Windows 10 automatically updated version of 486.0.0.0 from Oct 2020 with the driver found in Apple Mobile Devices. One of the listing refused and one of the listings let me update the driver. It immediately moved the listing to USB controllers. The driver is now listed as being version 6.0.9999.69 from 2017. The second listing is gone. I've restarted the PC and I can sync my iPhone with iTunes as many times as I want. I've restarted the PC a few times, synced multiple times in a row, restarted iTunes, used iTunes to force a sync over Wi-Fi... anything I can think of. All of the syncing is working and appears to be reliable so far. It's only been an hour, but I've never had any sort of change or success before. The only thing that isn't working the way it sounds like it should is iTunes isn't automatically opening when I connect my iPhone to the PC. I don't really mind. Looks like I fixed it. I figured I'd leave this here if anyone else is struggling with this. It figures I would stumble across the answer not during the months of struggling with this issue and running troubleshooting it but instead around an hour after posting for help.
