XAMPP is not designed for production use, I highly recommend you read this thread: https://community.apachefriends.org/f/viewtopic.php?p=192464 and other threads relating to this. You mentioned your deployment would be on a local network however if the web application will handle company secrets or sensitive information you should not use XAMPP unless every user is trustworthy. If you do use XAMPP, the company should know in advance they will need to port to a production ready web server to expose any part of the system online. If you are limited to Windows hardware you could use WSL2 to install Ubuntu (or other Linux distros) on a Windows system. https://docs.microsoft.com/en-us/windows/wsl/install

Hi

We use both. Normally nginx for frontend with load balancing and apache/IIS/.. behind it. It helps keeping servers and concerns decoupled.
