```python
from typing import Callable, Any

class FallbackExecutor:
    """
    A class for executing a function with fallback behavior.

    This executor attempts to execute a given callable. If an exception is raised,
    it invokes a fallback function to handle the error and return a default value.
    
    Args:
        func: The main callable to be executed.
        fallback_func: The fallback callable to handle exceptions and provide a default value.
        error_type: Optional; specific exception types to catch, otherwise catches all.

    Usage Example:

    >>> def divide(a: int, b: int) -> float:
    ...     return a / b
    ...
    >>> def default_value() -> float:
    ...     return 0.0
    ...
    >>> executor = FallbackExecutor(divide, fallback_func=default_value)
    >>> result = executor.execute(10, 2)
    >>> print(result)  # Output: 5.0
    >>> result = executor.execute(10, 0)
    >>> print(result)  # Output: 0.0
