If by wirelessly you mean via Wi-Fi network then one convenient option is qrcp. It generates a QR-code right in your terminal, which you can scan with a phone and send/receive files through a web interface on the URL it provides.
If you want to transfer files regularly, there is another option. Almost every distro has Python installed, and the Python has a “built-in” FTP server. You need to just cd into desired directory and run the command python -m pyftpdlib -w. It will open a FTP server with root in this directory. You then can access it through a file manager, like Material Files for example, and send files and folders back and forth. In Material Files you can save the server address for future use.
This + package to enable VSCode marketplace. The only VSCode features it lacks afaik are out of the box settings sync and remote container development, which colud be substituted with plugins.
EDIT: also be sure to check out Lapce suggested by Yote.zip - it’s a banger.
