Powershell - Move files to existing folders with partially matching names - windows

Question

I have a folder with images that multiple people will be contributing, and I have multiple folders that other people will be creating with additional content, the folder names will be similar but not identical to the file names (see example below). I have tried writing a Powershell script (I'm still a bit green with it) that moves each image to its respective folder but I hit a wall, I'm getting the "Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Destination'. Specified method is not supported." I tried converting the destination to a string but had trouble looping through the list of folders. I'm adding the code here in hopes someone will spot the error I made in the code and will point me in the right direction. Thanks in advance for taking the time to help.
$sourceFolder = Get-ChildItem 'C:\Example_Files_Folder' -Recurse -Filter *.png
$targetFolder = Get-ChildItem -Path 'C:\Example_Target_Folder' -Recurse -Directory
foreach ($file in $sourceFolder) {
Where-Object { $targetFolder.Name -cin $sourceFolder.BaseName }
move-Item -Path $file.FullName -Destination $targetFolder.FullName -WhatIf
Write-Output "...copying $file"
}

Continuing from my comment ...
You can simplify this to say something like this:
# Target folder tree
$targetFolders = Get-ChildItem -Path 'D:\Temp\Target' -Recurse -Directory
# Results
<#
Directory: D:\Temp\Target
Mode LastWriteTime Length Name
---- ------------- ------ ----
d----- 17-Feb-21 10:22 Book
d----- 17-Feb-21 10:10 TextData
Directory: D:\Temp\Target\Book
Mode LastWriteTime Length Name
---- ------------- ------ ----
d----- 17-Feb-21 10:10 Date
#>
# Source folder files to move
Get-ChildItem 'D:\Temp' -Recurse -Filter '*.txt' |
ForEach {
ForEach ($targetFolder in $targetFolders)
{
If ($PSItem.BaseName -match $targetFolder.Name)
{Move-Item -Path $PSItem.FullName -Destination $targetFolder.FullName -WhatIf}
}
}
# Results
<#
What if: Performing the operation "Move File" on target "Item: D:\Temp\Book- Copy (2).txt Destination: D:\Temp\Target\Book\Book- Copy (2).txt".
....
What if: Performing the operation "Move File" on target "Item: D:\Temp\DateData.txt Destination: D:\Temp\Target\Book\Date\DateData.txt".
