Small caps look official without shouting, which is why they suit disclaimers, footnotes and terms summaries. They are still unicode, so they paste into PDFs and email templates.
Use fontstyle.io for the label and keep the legal text in normal characters. Accessibility matters here: screen readers handle ordinary text far more reliably.
If the disclaimer is contractual, keep a plain-text version in the document as well.
