Can you give us an idea of how you're currently using the pick-flage, stars, and color labels? That might help us give better recommendations.

It took me a few years of using Lightroom before I evolved a system of using flags/metadata/stars that suited me. This was after a couple of false starts. I'm happy with my system now, but find it is a chore to maintain.
Same, although mine isn't too much of a chore to maintain.
Star ratings: How much I like the photo. One star or higher means I likely won't delete it, two stars will probably be finished/shared/published, three stars for my favorites of that set or session, five stars are portfolio material.
Pick flags: I apply the white Pick flag only on images that are processed, finished, and ready to export or publish. All Pick images should have at least one star, usually more.
It's rare that I use the black Reject flag; I usually just delete any that don't have any stars by the time I'm done culling and publishing the set. Sometimes I use the black flag on my first culling pass-through, for things that are definitely trash (misfires, missed focus, etc).
Colors: Blue means it's a keeper out-take, ColorChecker shot, behind-the-scenes, maybe something that's silly that I want to share with the subject but not publicly publish. Red and yellow mean they need work in Photoshop, for example, sets that will be merged to a panorama, a face-swap to fix a blink, or the occasional portrait that gets the "full treatment" (frequency separation retouching, etc). I'll sometimes use green on an ad-hoc basis.
For cataloging purposes, my folder hierarchy and file naming conventions do most of the work. I don't need to use the keywords, stars, etc when my folder tree and filenames do that work.
