Let's create the `initialize_arrays` function based on the provided specifications. This function will read data from a file and initialize arrays accordingly. For this to happen, the file structure and content need to be properly defined. Assuming a simple CSV-like structure for the file with process names, next-use time (NUT), and arrival times, the function would look something like the following.

```python
import os
import sys
import logging

# Set up logging
logging.basicConfig(level=logging.ERROR)
logger = logging.getLogger(__name__)

def read_and_validate_data_file(data_file_path):
    """
    Reads and validates the data file, ensuring it is a regular file.

    :param data_file_path: Path to the data file.
    :return: Data read from the file.
    """
    if not os.path.isfile(data_file_path):
        logger.error(f"Error: {data_file_path} is not a regular file.")
        sys.exit(1)

    with open(data_file_path, 'r') as file:
        lines = file.readlines()

    data = []
    for line in lines:
        if not line.strip():
            continue  # Skip empty lines
        parts = line.split(',')
        if len(parts) < 3:
            logger.error(f"Error: Line in data file does not have enough parts: {line}")
            sys.exit(1)
        try:
            name, service, arrival = parts[0], int(parts[1]), int(parts[2])
            data.append((name, service, arrival))
        except ValueError as e:
            logger.error(f"Error parsing line in data file: {e}")
            sys.exit(1)
    return data

def initialize_arrays(data_file_path, quanta):
    """
    Initializes arrays based on the data from the file.

    :param data_file_path: Path to the data file.
    :param quanta: The quanta value to be used in quantaArray.
    :return: Dictionary containing all initialized arrays.
    """
    data = read_and_validate_data_file(data_file_path)

    # Initialize arrays based on file data and specifications
    name_array = [name for name, _, _ in data]
    service_array = [service for _, service, _ in data]
    arrival_array = [arrival for _, _, arrival in data]
    priority_array = [0 for _ in data]  # Default to 0 as per specifications
    status_array = ['-'] * len(data)  # Default to '-' as per specifications
    reference_index = list(range(len(data)))  # Integers 0 to n-1
    new_queue = []  # Empty as per specifications
    accepted_queue = []  # Empty as per specifications
    quanta_array = [quanta for _ in data]

    arrays = {
        "name": name_array,
        "service": service_array,
        "arrival": arrival_array,
        "priority": priority_array,
        "status": status_array,
        "reference_index": reference_index,
        "new_queue": new_queue,
        "accepted_queue": accepted_queue,

    return arrays

if __name__ == "__main__":

        print("Usage: python script.py <data_file_path>")
        sys.exit(1)

    data_file_path = sys.argv[1]
    quanta = 1  # This can be set to another value or passed in as an argument.

    arrays = initialize_arrays(data_file_path, quanta)
    for array_name, array_values in arrays.items():
        logger.debug(f"{array_name}: {array_values}")
```

Please note that when working with actual data files and user input, further validation and error handling might be necessary to ensure the robustness of the script. The code above assumes a data file with process information and creates arrays to store various process attributes, such as names, service times, and arrival times, along with initializing other arrays to default values as specified in the original instructions. The `logger.debug` calls show the contents of the arrays when the script is run in debug mode.
