I second Create: Above and Beyond!! I’ve been playing it with a friend, it’s got a fun progression with plenty of processing. Early game is rough— I recommend exploring natural generated structures for iron and stuff before really diving into the automation.

Note that it’s still a fairly “kitchen sink” modpack. The magic mods feel especially slapped on there. It also has computercraft and tinker’s construct, which aren’t really integrated with the main progression. If you’re looking for a consistent style with less complexity to start, it might be worth playing Create 1.20.1 on its own or with a few “vanilla+” mods. Create has a “ponder” feature that can teach you how to use basically every part of the mod.
