Honestly, The Dream (So to speak) would actually be achieving All-XX before the game ends, but that might be a bridge too far.
Let's do the math! After this update we'll be at:
Food Production 15 (0/2)
Civilian Infrastructure 16 (0/2) - [2x 50% Discounts]
Heavy Industry 15 (0/2)
Void Industry 17 (1/2)
Medical Services 16 (0/2) - [1x 50% Discounts]
Military Industry 15 (0/2)
So we'd need a total of
10+3 (ISC)+10+5+7+10=45 actions to get there.
But we can get another Planetmaw to drop that again, I think? That was only 6 actions before. It might be the same, or it might be different. Still, it's in the realm of 4-8 actions with unto Works Generational, and after that we'd need:
5+2+5+3+3+5=23 actions. So somewhere in the regime of 30 actions total.
A single unenhanced turn is 4 actions, and a full general turn with Cry for the Future is 7. So in the regime of 7ish turns of fairly dedicated effort. Which... honestly. I'd prefer to unify with the Shipwrights and the Council. We're already tall, and the way to maximize volume would be to go a bit wider, and that means integrations/unions with our neighbors. It's one thing to be a little polity with a hundred stars but super-advanced society, but if instead control 500 stars with very advanced society and continually acquire more through integration, diplomacy and occasional conquest of assholes, that's a nation that is more likely to shake up the galaxy.
Notably, just getting to Void Industry XX is going to be 5 total actions without the planetmaw, and 3 actions with it. So it's not worth getting unless we want to get everything to XX. And that's a single turn with Cry up. I could easily see us getting all-XV, and then if we can leave Cry on for one more turn we can get Void-XX immediately.
