Depends on the page itself (sorry to barge in), some templates automatically add them when you use them (notably the writer template and infoboxes) otherwise it varies on how you want to do it.

Key ones might include the universe (in my work's case "Solar Era", or otherwise Cosmic Era, Universal Century etc.), from that you might also want to include an in-universe category (e.g. Cosmic Era Characters, Cosmic Era Mobile Suits etc.) and notable factions they belong to. Genetic type might also be one to consider and gender is automatically added by the character infobox.
