Confused About HR Roles: Facilitator, Policy Maker, Employee Advocate, or Business Partner?

Dear All,
I am a little confused as I have not got a lot of experience. I need a little clarity on the role of an HR professional. Kindly share your thoughts on the following: What, according to you, is the role of HR?
AS A FACILITATOR: They help in facilitating a lot of processes (Training, PMS, mentoring, etc.).
AS A DISCIPLINE ENFORCER/POLICY MAKER: Policy-making as per the requirements based on principles.
AS AN EMPLOYEES PERSON IN ORGANIZATION: Like a marketing person has a very good relationship with the client and the client feels that the Marketing guy is their guy. In return, the marketing guy gets a lot of repeated business and references.
So, should an HR person be the employees' guy in the organization?
AS A BUSINESS PARTNER:
OR SOMETHING ELSE.
If you have to choose only one role, which role would you CHOOSE?

In organizations, the role of an HR professional is multifaceted. They act as facilitators, policy makers, employee advocates, and business partners. Each role is crucial in ensuring the smooth functioning of the organization and fostering a positive work environment. If I had to choose one role, I would prioritize being an employee advocate. Building strong relationships with employees, understanding their needs, and championing their rights within the organization can lead to increased employee satisfaction, retention, and overall organizational success. Being the employees' person can create a culture of trust, loyalty, and engagement, which are essential for a thriving workplace.
