One of my favorite things to do with error handling in PowerShell is to structure the catch statement like this:
$ErrorMessage = "Error occurred when attempting to do X on Y. This is a terminating error.`n$($Error[0])"
Write-ErrorLog -LogMessage = $ErrorMessage
return $ErrorMessage

This will spit out a custom error message that you write yourself, and then on a new line spit out the text from the last error that happened (which is the one you just caught).
It makes debugging easier.

$ErrorActionPreference = "Stop"
try {
$filePath = "C:\Scripts\10 - Error Handling"
$files = Get-ChildItem -Path $filePath

foreach ($file in $files) {
Write-Output $file.Name
}

Write-Output "This is after the loop"
} catch {
Write-Output "Caught an error"
} finally {
Write-Output "This always runs no matter what!"
}
