Example Code

from typing import Optional, Annotated

import logging
import typer as t
from enum import Enum

root = t.Typer()

class LogLevel(str, Enum):
    """LogLevel enumeration.
    """
    DEBUG = 'DEBUG'
    INFO = 'INFO'
    WARNING = 'WARNING'
    ERROR = 'ERROR'
    CRITICAL = 'CRITICAL'

@root.command()
def _root(log_level: Annotated[Optional[LogLevel], t.Option(case_sensitive=False)] = LogLevel.WARNING):
    if log_level:
        logger = logging.getLogger()
        logger.setLevel(log_level.value)

Description

Here's what I get in --help for the above code:

--log-level                 [DEBUG|INFO|WARNING|ERROR|CRITICAL]  [default: LogLevel.WARNING] 

The displayed default value uses the Python enum notation.
I'm expecting to see a user friendly "default: WARNING" instead.
