Expected:
When an input has a programmatically associated label and an aria-label attribute or aria-labelledby attribute, based on the accessible name computation the aria-label or aria-labelledby attribute should take precedence over the programmatically associated label. 

Actual:
VoiceOver on iOS, reads the programmatically associated label instead of the accessible name provided via the aria-label or aria-labelledby attribute
Applies to input types: text, password, search, tel, email and url

On macOS Catalina Version 10.15.5 works as expected - aria-label or aria-labelledby attribute takes precedence over the programmatically associated label.

if we don't expose the titleUIElement, should it even be in the accessibilityText that's generated?

This is used for aria-label, so you can have a form field, for instance, with aria-label="blah" and we want to return "blah" if there is no titleUIElement. It seems that the precedence of titleUIElement over aria-label was established at some point, but I have not check what the aria spec says about this, if any thing.
