I write a lot of meta abstractions myself, because ... I'm lazy :). But there is no standard pkg/lib I use anymore usually I add things to a project and extract them as libraries if I need them again.
Often they are framework specific traits like "ApplicationLogTrait" or something. nothing fancy. just a getter for my logging which I fetch from a registry pattern or a parser / transformers such tedious "match that, turn it into" things like "camelCase to snake_case to kebab-case" or "create a cache proxy for class XYZ".
But as I mentioned I write a lot of this stuff myself and just throw it into the pkg managers not carrying if anyone else uses it ;D ....
