Does Ace Combat 8 use first-person story scenes?
Yes. Between aerial missions, the campaign uses first-person cinematics aboard locations such as the carrier Endurance.
Confirmed explanation
Project Aces uses the perspective to show conversations, squad relationships and the burden of inheriting the Wings of Theve identity. It is a storytelling camera, not confirmation of on-foot combat.
What is not confirmed yet
Scene interactivity, dialogue controls and whether every intermission uses first person are not fully documented.
