Being a paralegal won’t make you stand out. There will be 100s of other applicants with paralegal experience or similar work experience applying.
someone’s individuality will come through a combinations of experiences, strengths, motivations and learnings. I would expect an answer like this to talk about that combination that makes someone unique.
I wouldn’t necessarily also try and “fit” into competencies the firm is trying to assess - this is about the additional things that bring flavour to your application and make you stand out. Every candidate will be able to fit into the competencies and therefore by default, not stand out.
By "experiences, strengths, motivations and learnings" what do you specifically mean? There is another question asking about interests you pursue outside of law so don't want to repeat those.
