Stuck: Best minimalist font pairings for a modern tech brand?

I'm designing the brand identity for a new minimalist tech startup and am completely stuck on font selection. I need a pairing that feels both incredibly modern and clean, but also has a subtle warmth or approachability. Every sans-serif combo I try feels either too generic or too cold. What are your go-to, proven font pairings or methods for achieving this delicate balance without overcomplicating things? Really eager to hear some fresh perspectives!
