Glad to see Dunlop Super Brights getting some mentions here. They'd be at or near the top of my list for your needs, OP, thanks to their great mid-range character. The Super Bright moniker isn't specifically about the highs; they're are what I'd call full-spectrum strings. In light-bulb terms, they're bright white, even the nickels.
But no, I'll look further. Perhaps the Dunlop bright nickels or the NYXLs.
