I came in from Champions/HERO too.
The element from HERO to bring here, I think, is to treat the Powers, and especially the Abilities, in SCRPG as purely mechanical bits, that can be entirely reskinned to fit the character you're creating. In HERO, your character build might have a mechanical bit Energy Blast 12d6, but that's driven by your character having a Lightning Strike or TK Punch -- the mechanics-layer follows the fiction-layer.
IMO, ignore the random-rolled character creation system completely unless your only goal is to create a random character. Random character creation is an early 1980s anachronism, and really doesn't belong as a centerpice of character building in a game released in 2020. And yes, that's blunt, but it's blunt for a reason. If anything, the focus on the random element just makes SCRPG's creation system more obtuse and arcane.
If you're following the constructed method, pick the elment at each stage that best provides the mechanics you need to model the character's capabilities, and then rename them ALL if that's what it takes.
