How to change the player's forward direction and make turning more smooth

Hi! Thanks for taking a minute to read my question.

So I have a player model with a camera attached to it and that is controllable by the arrow keys. When I change direction, I would like the direction that the player is facing to be "forward". So if I turn to the right, I would like the forward arrow key to control the movement forward, and not the right key as it does now. How could I do this?

Also, how could I make the turning more smooth in the process? It's a little jerky and somewhat disorienting.

Here's my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerController : MonoBehaviour
 {
     public float turnSpeed = 1f;
 
     Animator m_Animator;
     Rigidbody m_Rigidbody;
     Vector3 m_Movement;
     Quaternion m_Rotation = Quaternion.identity;
 
     void Start()
     {
         m_Animator = GetComponent<Animator>();
         m_Rigidbody = GetComponent<Rigidbody>();
     }
 
     void FixedUpdate()
     {
         float horizontal = Input.GetAxis("Horizontal");
         float vertical = Input.GetAxis("Vertical");
 
         m_Movement.Set(horizontal, 0f, vertical);
         m_Movement.Normalize();
 
         bool hasHorizontalInput = !Mathf.Approximately(horizontal, 0f);
         bool hasVerticalInput = !Mathf.Approximately(vertical, 0f);
         bool isWalking = hasHorizontalInput || hasVerticalInput;
         m_Animator.SetBool("IsWalking", isWalking);
 
         Vector3 desiredForward = Vector3.RotateTowards(transform.forward, m_Movement, turnSpeed * Time.deltaTime, 0f);
         m_Rotation = Quaternion.LookRotation(desiredForward);
     }
 
     void OnAnimatorMove()
     {
         m_Rigidbody.MovePosition(m_Rigidbody.position + m_Movement * m_Animator.deltaPosition.magnitude);
         m_Rigidbody.MoveRotation(m_Rotation);
     }
 }

Thanks in advance!
