Search internal pages quickly? / Pages Panel Organization & Searchability

Site URL: https://www.fwdcollective.io

Hi - Looking for tips/guidance on how to search my internal pages in my pages panel on my site(s) quickly and efficiently. 

The number of pages on my site and some of my client sites are starting to get a bit unruly. I tried folders but index pages don't go into folders it appears. Are there ways to search internal pages? Or a trick or navigation setup best practices that I'm missing?
