I tried all sorts of different ways to store and use my scraps and it turned out I didn't really enjoy any of them. I did not have the wise eyes of a child to help me but decided I simply just wasn't going to do it any more -- lol well sort of. I no longer keep pieces smaller than a 6.5" square on the theory that I can cut down but I can't cut up. I have one tote for those 6.5 strips. Every now and then I'll color sort them, but I haven't found a really great system because sometimes I want a particular theme (geometric, floral, civil war, on and on).
You have a guild with a free table, I found a quilter here on the boards who was playing with crumb quilts and I'd send her a box of little pieces once/twice a year. I just kept the box at my cutting station.
A lot of people use 2.5" strips, it rather scared me when I realized that like you, I could spend the rest of my life doing nothing but sewing quilts made up of that jellyroll size. Some people like that idea, it rather scared me... and zoom! out went all the smaller strips. Freed me up to do the projects I wanted to do, even if I have to cut a bunch of 2.5" strips,
The other thing about scraps is do you like working with scrappy projects?? I was helping one of my dear friends do some organizing before I left the Seattle area. She had boxes and boxes and boxes of tiny little scraps but never made projects that way. It was much more fun for her to choose a few pieces of yardage from her large stash instead. I never did convince her to lighten the load of the fabric she really wasn't going to use anyway but I planted a seed and we did organize a lot of the bigger pieces and put together themes like various holidays and neutrals and 30s (both real and reproductions) etc.
In addition to the storage issues I also had the idea that I had to use them in the best possible way... I have determined that the best use is any. When I come across a scrap left from a special project (and yeah, I do remember a lot of them) I'd hold it and remember my god-child in a dress 30 some years ago and say it was time for this scrap to find it's own way.
