Creating FAQs can be a powerful tool to help your customers find what they're looking for, and can have huge SEO benefits.
The best way to create FAQs is as posts — each question is a "blog" post which can be seen in an FAQs blog. Then you can reference these posts in your sections/templates and pull information into sections dynamically (like accordions). This can be powerful as you start to build a "library" of new FAQs.

A well-written question and answer with relevant keywords can help search engines understand the main subject of your content, leading to better rankings. It goes without saying that you can and should add relevant links to your content to provide additional information or references. Use bold/strong settings to highlight important text which you want to emphasize for your reader. You can also use italic/emphasis tags to emphasize something specific, adding subtle highlights to your text.
