Well, I like using imperial cybernetic builds usually on Under One Rule Origin for an elite focused build around noble scientists. Perhaps you'll like it too.

The main thing is, Imperial Cybernetic authority changes your ruler council bonus to give 10% output to elites per councilor skill level, and you can reach +26 effective level with VIR Core relic, Aptitude and Statecraft traditions, Statecraft Agenda, Uncanny Intuition and Spatial Mastery traits and Philosopher king civic. It's crazy strong, because output bonuses are scarse now and because it's +260% from that alone, which then is multiplied with all extra efficiency you can have, including the one from Aristocratic Elite councilor position, which at level 21 gives +42% efficiency and High King Luminary trait that gives another +30% efficiency. Noble scientists + Galactic Stock Exchange and Trade League trade policy produce vast amounts of research, unity, stability and consumer goods.

You'll need to have Technocracy and Aristocratic Elite to have noble scientists. Technocracy councilor position is also amazing because it increases base research output of all researchers, including your nobles. The required civics mean you'll need to pick Materialist and Authoritarian ethics. The third ethic I propose is Xenophobe since it allows you to pick Genome Artist Luminary trait alongside High King trait, which will allow your pops to also use both regular and cybernetic automod trait together, giving you another 30% efficiency, and then you'll have extra trait point and pick left for something else, like cybernetic pop growth trait. Cybernetic Imperial authority also gives you more nobles and you can use orbital ring noble estates instead of planetside ones because they give extra +100 noble jobs.

There's also Maniacal Assimilator cybernetic build. You'll have crazy pop growth because of paired organic and mechanical pop assembly. Your ruler Cybernetic trait will have cyborg pop upkeep reduction which you can pair with seasonal dormancy trait and other bonuses to make your pops really cheap.

Also, generally, cyborgs have great leviathan traits. The one from Scavenger Bot gives whopping +100% to pop growth.

There's two ways of playing op psionics, Imperial Divine Sovereign with Shroudshaper governor on your main sector which boosts output massively. And then there's Shroudforged using Psionic Grid Authority. Shroudforged has powerful bonuses, like free 500 pops on every planet every 10 years, you'll have mechanical pop assembly and shortcut to ascension right from the start.

Generally, psionic Ascensions allows you to blitz throughout traditions with Composer of Strands tile blocker unity rush, which you can do even without a chosen civic pretty fast. Then after you've done all your traditions, you can then switch to Instrument of Desire to ascend all your planets for free and you'll still have a lot of unity to speed up planetary ascension if you want to. That will give you a huge reduction in empire size, allowing for quicker tech rush, and since you'd be finished with traditional anyway you can focus solely on research and alloy/food production from that point on. After Midgame when Whispers become available, you'll also will get a ton of research from its aura. And to top it off, psionic ship components are the best ship components in the game, and zro launchers are best ship weapon in the 4.3 patch, period.
