Coming back after ~1.5 years — mods and ready-made modpacks recommendations?

[Rrostayk]

Hi everyone!

About a year and a half ago I made my very first post here asking for mod recommendations as a total beginner, and the community gave me an amazing list. Since then a lot has changed — the game got updates, Space Age has been out for a while, and the mod scene has clearly moved on.

Now I'm coming back and I'd love to hear what's good right now:

Individual mods — anything you'd call a "must-have" over the last year, quality-of-life or bigger stuff, just throw them at me.
Ready-made modpacks / curated collections — if there's a pack you can just install and play (a Mod Portal collection, a shared mod-list/sync file, a known "recommended set"), that would be great too. Links welcome.
Any good overhaul mods worth a full playthrough?
What plays well with Space Age specifically (compatible + actually fun)?
Any hidden gems that came out recently and don't get enough attention?
I'm open to both quality-of-life stuff and heavier challenge/overhaul runs. Links and short "why I like it" notes would be super appreciated.

Thanks in advance, and may your production chains be flawless!
