A family of Microsoft word processing software products for creating web, email, and print documents.
You could test one or two cross-references to see whether they remain stable and do what you want. The main difference is that, whereas you can use any display text you want for a hyperlink, with a cross-reference to a heading you're limited to the heading text, heading number, page number, or "above/below." Also, the cross-reference, though hyperlinked, won't be formatted as a hyperlink (the Hyperlink style is applied but suppressed), which makes it less obvious that it's a link. On both counts, it appears a hyperlink is more suitable for your purposes. Both HYPERLINK and REF fields may need to be updated manually if the heading changes.
