See multiple ways to obtain ILogger in Azure Functions 6 from docs and templates, what are the differences?

Question

I'm using Azure Functions 6 (.NET 6, isolated), with Application Insights enabled.

From different versions of Visual Studio, Azure Functions Core Tools, the default Microsoft templates and other docs showed a variety of ways to obtain ILogger. I've seen:

1. Constructor injection of ILoggerFactory (from a default MS template):

private readonly ILogger _logger;

public MyFunction(ILoggerFactory loggerFactory)
{
    _logger = loggerFactory.CreateLogger<MyFunction>();
}

2. Getting it from the FunctionContext (also from default MS template):

public async Task<HttpResponseData> Run([HttpTrigger(...)] HttpRequestData req, FunctionContext executionContext)
{
    var logger = executionContext.GetLogger("MyFunction);
}

3. Injecting ILogger directly into the Run method:

public static void Run(EventGridEvent eventGridEvent, ICollector<string> outputSbMsg, ILogger logger)

4. Regular ASP.NET Core constructor injection of ILogger<T>:

private readonly ILogger<MyFunction> _logger;

public MyFunction(ILogger<MyFunction> logger)
{
    _logger = logger;
}

What are the differences of all these methods and which ones are the best to use?
