        "font-size": "20px",
        "font-weight": "bold"

enter image description here

I had similar requirement. I customized my list in Power Apps. If you are not willing to use Power Apps, change List Settings -> Advanced Settings -> List Experience to Classic experience and script in newform.aspx
