App Store will not return to Home Screen.

Did that already, still didn’t come back.

If you tried resetting the Home Screen Layout, my next suggestion would be to back up the phone then restore it to factory settings. Check for the App Store. If it's there, restore your backup and check again.

Ideally, you would do the restore to factory settings using a computer, not iCloud. When you do that, it downloads a new copy of iOS.

You cannot delete the App Store. Swipe all the way to the left to reveal the App Library and type in “App Store” to add it back to one of your Home Screens. If it’s not there, check Settings > Screen Time > Content & Privacy Restrictions > iTunes & App Store Purchases > Installing App.

If you truly have tried all the other options you stated, try a full factory reset with a back up. Go to Settings > General > Transfer or Reset > Erase all Content and Settings. Remember to back up your device before so you will be able to load back your data when the factory reset is complete. How to factory reset your iPhone, iPad, or iPod touch - Apple Support

There are multiple reset options. Resetting to factory settings does not delete any data, just changes all settings back to their default.

No, that's Settings>General>Transfer or Reset iPhone>Reset>Reset All Settings. It's not restoring the phone to factory settings. They are VERY different. But semantics aside, try the instruction I just linked to. Back up first, of course.

Before considering doing a factory restore or erasing all content and settings, I suggest resetting the Home Screen Layout. Settings>General>Transfer or Reset iPhone>Reset>Reset Home Screen Layout. While it will remove any folders you've created, it will not delete any data or remove any other customizations. It will return the factory-installed apps to where they were when you first activated the phone. Third-party apps will be alphabetical.

Ok, so I finally bit the bullet and did it. Wiped her phone. Erased all data. . .

finally got it all set up again and signed into her Apple ID to restore everything.

Did you test it before restoring the data? If it was there before you restored the data and missing afterwards, that would suggest that there is a problem with her data.

Does she have any school or work accounts on the phone?

It appears that you’ve tried all your options repeatedly. I recommend reaching out to Official Apple Support. They have the expertise and resources to address this matter at a level and provide you with a satisfactory result, all we can provide is our insights and support provided by Apple.

BTW, when I reset the Home Screen id did bring back all of the standard apps just like you said, except the App Store 🤦🏼‍♂️

Still not in App Library or showing up in search results. Screen time setting remained the same. Downloading. . . All enabled.

Yup, that is not a factory reset. But, it certainly didn't hurt that you tried. At this point, I really thing that restoring it to factory settings using the link I provided above is the way to go.

I reset it to factory settings. Still no luck. I have a feeling I may need to backup her phone and wipe it.

Resetting to factory settings means you wiped it completely clean and returned it to the state it was in when you took it out of the box. But it sounds as if maybe that's not what you did?
