I'm a beginner guitar player and I have been told that starting off without power chords is generally a good idea, the reason being that I have trouble keeping my fingers on the correct string when sliding. So I am looking for punk rock tabs without power chords to get my fingers used to moving.

I'm not sure I understand your issue. All punk rock is is pretty power chords, so if you have a problem with sliding power chords just work on this exact technique. And if you want to play something that doesn't involve it just search for a melodic riff.
