I have it basically setup. See name properties output below.

The below is from the Modern Combo Box Properties:

DefaultSelectedItems = ThisItem.PermitOwner

Items = Choices(EnvironmentalPermits.PermitOwner)

The code for the DataCard Properties:

DataField = PermitOwner

DisplayName = DataSourceInfo(EnvironmentalPermits,DataSourceInfo.DisplayName,PermitOwner)

Update = DataCardValue26_1.Selected

None of the above worked.

I also tried various code from the internet as well. For example, using the below in the update of the data card

{
Claims: "i:0#.f|membership|" & Lower(ComboBoxName.Selected.Mail),
Department: "",
DisplayName: ComboBoxName.Selected.DisplayName,
Email: ComboBoxName.Selected.Mail,
JobTitle: "",
Picture: ""
}

See image below from the area of my Form in question

Lastly, I only want to pull the DisplayName from the user. Is this possible? I'm sure it is. I'm probably not adding something. Thanks in advance for your help!

@TS-17021950-0,

Pick from what’s already in the list
If you truly want only people already used in the list column, keep Choices(List.PersonColumn). Then Power Apps can submit the selected record directly without reshaping:

Items = Choices(EnvironmentalPermits.PermitOwner)
DefaultSelectedItems = ThisItem.PermitOwner

Update (single‑select) = DataCardValue_PermitOwner.Selected

This works because the Choices() output and the SharePoint Person field schema already match. Just know you’ll likely not see your entire directory; this can be confusing and is why many switch to Office365Users.

Common issues to check

Single vs Multi‑select

Single: use .Selected in Update; Multi: use ForAll(SelectedItems, …) and return a table of claims records.

Modern Combo box “shows numbers”

Fix the Fields mapping (Primary = DisplayName, SearchField = DisplayName/Mail). Modern controls are still maturing; this mapping is required.

Default only for New mode

Use If(Parent.Mode = FormMode.New, <claims record>, ThisItem.PermitOwner) to avoid overwriting existing values.

Delegation & large tenants

Choices() won’t scale to thousands of users; use Office365Users.SearchUserV2 and filter/search as you type.

// Combo box Items (full tenant)
Office365Users.SearchUserV2(
  { searchTerm: Self.SearchText, isSearchTermRequired: false, top: 999 }
).value

// Combo box DefaultSelectedItems
If(
  Parent.Mode = FormMode.New,
  Blank(),
  ThisItem.PermitOwner
)

// Data card Update
{
  '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedUser",
  Claims: "i:0#.f|membership|" & Lower(DataCardValue_PermitOwner.Selected.Mail),
  Department: "",
  DisplayName: DataCardValue_PermitOwner.Selected.DisplayName,
  Email: DataCardValue_PermitOwner.Selected.Mail,
  JobTitle: "",
  Picture: ""
}

You can display only the DisplayName, but you must store the full person record in SharePoint. Show names in the UI via …Selected.DisplayName, but keep the claims record in Update.
Your earlier claims record attempt is correct approach; just pair it with Office365Users-based Items and ensure Fields mapping is set so the Combo box shows real names.
