Well, in terms of power, she'd definitely by final boss territory, like still a challenge for when your entire party is stupidly powerful, whereas the Demon Lord would be in endgame territroy for the end of the campaign, but she would still be weak enough for a possibly underleveled party who has arrived to defeat her, while she would still be weaker than many bonus bosses for the after-campaign bameplay.

Her move set would likely let her summon her own mooks, probably Angels or something similar, and be able to buff them to stupid levels, and probably some powerful debuffs for your party. Meanwhile would also be devastating lots of damage for the entire party, or single hits that would leave you with hardly any health left, using holy or celestial power, light, lightning, earthquakes. But, she would likely be very weak against say dark based attacks, and in this world, probably anything that might get her aroused.

Crazy fan-theory time, perhaps the Demon Lord will be forced to use her husband to seduce the Chief Goddess to end the war, but will be caught between the need to end the war and help secure the future of Human and Monster Kind, and the desire to keep her Husband all to herself.
