In a point wrangle, I'm trying to find the nearpoint in Input 1, but I'd like each point in Input 0 to look in a specific direction (a cone around a vector attribute) and ignore points in other directions. Anybody has a general idea on how to get started with this?

One way might be using nearpoints() function and filter the point list by angle to a direction.

It should work in any contexts that allows VEX shaders
So even POP DOP nodes that support VOPs or VEX snippets. if that's what you refer to as POPs
