I'll use aperture-Priority Auto (A)mode. I like to use F 5.6 /8
Regardless indoor or outdoor, I use flash to fillin or muti flash. If you want flare effect. Use bigger aperture. But you have to watch out the shadow. You can see a lot of 人像 pic is too bright. No detail on the face. I guess they apply too much cosmetic on their face. This reflect more light on the face.
Good luck.
