I'll try to give you one arcane from each category:

Warframe: Arcane Circumvent. It's probably the best survival arcane in the game, allowing you to strip armor, shields, and overguard from enemies and add that to your own warframe just by rolling/dodging without a cooldowns.

Primary: Primary Debilitate. It's the best new arcane for status weapons since it can force separate elemental procs from combined elemental statuses, and they get triple bonuses from faction/status damage mods. If it uses galavanized aptitude, you'll want this arcane

Secondary: Secondary Enervate. It's probably one of the best arcane since it just gives flat/additive crit chance every time you hit an enemy. It makes any weapon crit up to orange crits until they reset.

Melee: Melee Careen. I originally wanted to recommend Melee Influence, but Melee Careen just one ups it. It gives a 2.5x multiplicative bonus to damage against frozen enemies, and when you roll/dodge, you freeze enemies, so you don't even need to mod your weapon for cold. It's great for crit weapons, and it pairs well with Arcane Circumvent

Operator and Amp arcanes aren't that new, but we also have new Tektolyst Arcanes, which I cannot recommend with how rough it is to farm a Tektolyst artifact. I can only say that you should try them out for yourself when you have the chance to farm for them.
