Movement really slow in Unity

Question

I'm working on a very basic side scrolling platformer in Unity 3D. The player is a cube, you can move left and right, you can jump. I can't get the movement correct as the character moves too slow.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{
    public float walkSpeed = 15f;
    public float jumpSpeed = 15f;
    public float gravity = 50f;
    
    Rigidbody rb;

    bool pressedJump = false;

    Vector3 movementInput;
    
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void Update()
    {
        movementInput = new Vector3(Input.GetAxis("Horizontal"), 0f, 0f);
    }
    
    void FixedUpdate()
    {
        WalkHandler();
        
        JumpHandler();

        GravityHandler();
    }
    
    void WalkHandler()
    {
        rb.velocity = new Vector2(0f, rb.velocity.y);

        rb.velocity = movementInput * walkSpeed * Time.fixedDeltaTime;
    }
    
    void JumpHandler()
    {
        if (Input.GetButtonDown("Jump"))
        {
            if (!pressedJump)
            {
                pressedJump = true;
                
                Vector3 jumpVector = new Vector3(0f, jumpSpeed, 0f);
                
                rb.velocity = rb.velocity + jumpVector;
            }
        }
        else
        {
            pressedJump = false;
        }
    }

    void GravityHandler()
    {
       rb.AddForce(Vector3.down * gravity * rb.mass);
    }
}

More context I originally had this implemented and it worked. Very smooth movement and jumping. I tragically lost that game due to my own actions. So I'm trying to recreate it. Here is a video of the original movement and jumping I'm looking to recreate:

My Progress so Far

Note: The values for walkSpeed, jumpForce and gravity were what was used previously.

Losing the first game was pretty soul crushing so any help would be great.

Have you tried increasing walkSpeed in the inspector while you play? — Daniel
Yes. 150 is much closer to the original movement but is 10x the original required value. Feels like the math or setup is wrong. — Kylee

OK so I'm not sure how to recreate this using velocity but this seems to work:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{
    public float walkSpeed = 15f;
    public float jumpSpeed = 15f;
    public float gravity = 50f;
    
    Rigidbody rb;

    bool pressedJump = false;

    float hAxis;
    
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void Update()
    {
        hAxis = Input.GetAxisRaw("Horizontal");
    }
    
    void FixedUpdate()
    {
        WalkHandler();
        
        JumpHandler();

        GravityHandler();
    }
    
    void WalkHandler()
    {
        rb.velocity = new Vector2(0f, rb.velocity.y);
        
        Vector3 movement = new Vector2(hAxis * walkSpeed * Time.deltaTime, 0f);
        
        rb.MovePosition(transform.position + movement);
    }
    
    void JumpHandler()
    {
        if (Input.GetButtonDown("Jump"))
        {
            if (!pressedJump)
            {
                pressedJump = true;

                Vector3 jumpVector = new Vector3(0f, jumpSpeed, 0f);

                rb.velocity = rb.velocity + jumpVector;
            }
        }
        else
        {
            pressedJump = false;
        }
    }

    // Check if the object is grounded
    bool CheckGrounded()
    {
        return true;
    }

    void GravityHandler()
    {
       rb.AddForce(Vector3.down * gravity * rb.mass);
    }
}

Ignore the CheckGrounded method
