Hey all looking for some party advice (again) - largely related to soul weapons but numbers/skill question as well

I keep going back and forth on what's the optimal opening for my dark party. Likely never make a difference, but the fact that I don't know is annoying me heavily. My party is:

Soul (currently herc - not sure who to make resident soul)
Thanatos
Satan (awakened)
Pluto
Amon (Unleashed)

sniper shot --> hades destroyer is a given, but after that I'm at a loss. Satan only applies dark resist down but I know that can be a massive damage boost. Pluto needs to use amphael giazza (wtf name is that?) to apply blocks before buffing for the added dark atk up, and thanatos provides an additional def debuff. I'm sure a lot of this is heavily dependent on gear, but I guess the general question is when applying debuffs, what are the priorities to use first? I've currently been going with Pluto --> Satan --> Thanatos due to debuffs being possible to miss and feeling like dark resist down > 3rd defense down debuff, but unsure if this is true or not. Also - is Herc the right soul for this comp or should I swap to Shingen or something?

My light comp is kinda bad (only have Michael and just got Moonlight Artemis), but was wondering what the go-to soul for light is in general. Comp is:

Herc
Uzume
SSR Artemis
Forseti
Michael

Love the burst gauge stacking, but doesn't seem like Shingen would work as they have long cds. Anywho any/all advice appreciated thanks!
