Which is your "Must Have Arcanes" list?

I'm "kinda old" player that stopped at around 2018 when The Plains and Fortuna were introduced. Now I'm back. I've done all the new quest. I'm Leveling up the new factions stuff, unlocked SP and arbitrations, currently going for more End Game content like Void Cascades and unlocking incarnon weapons.

But something that i really have no clue of what's good/useful or helpful are arcanes, besides Energize and Aegis which i already have.

And i would like to hear your thoughts on Arcanes that are must have for frames, weapons and operator so i can make a plan and either buy or farm. Even maybe something that could be niche. Like i know Camisado it's kinda good for Nekros (i love Nekros). But yeah that's basically it. Thanks y'all.
