"Figure out the guest box's IP address and output it"
If you enable RDP (Remoed Desktop) with:
vboxmanage modifyvm homeassistant --vrde on
(You'll probably have to reboot the virtual machine unless you ran this command before starting the vm)
Then you can RDP to the guest using the host's IP address. The RDP would have to originate from a machine with a GUI
Once in the guest at the ha> prompt, execute
net info
This should provide the guest's IP address

The options of which you write could be setting bash variables at the beginning of the script.
One of them could be the name for the virtual machine, eg.
VM=HomeAssistant
and then replace homeassistant with $VM
If you want the wifi interface it can be extracted into the variable $HAIF with the command:
export HAIF=$(nmcli d | grep wifi | awk '{print $1;}')
I don't believe you need to have the --nictype when using bridgedadapter thus

# Create the bridged adapter (DONE: Figure out a way to detect the netwerk adapter, or add it as an option)
# Network medium, NM: **wifi** or **ethernet**
NM=wifi
VM=HomeAssistant
export HAIF=$(nmcli d | grep $NM | awk '{print $1;}')
VBoxManage modifyvm $VM --nic1 bridged --bridgeadapter1 $HAIF

# Description:
# This script automates the deployment of a Home Assistant virtual machine (VM) in VirtualBox.
# It checks the latest Home Assistant OS release version from GitHub, compares it to the locally
# installed version, and creates a new VM if the latest version is not already installed.
#
# Key Features:
# - Dynamically fetches the latest Home Assistant OS release version using GitHub API.
# - Compares it with the currently installed local version.
# - Automatically downloads, extracts, and configures the latest version as a VirtualBox VM.
# - Ensures that VM configuration parameters (e.g., memory, CPUs) are pre-set.
# - Supports user confirmation before proceeding with download and deployment.
