My short answer is yes, I would buy any of the above. :-) I just bought two bags of someone's scrappy stash from a thrift store. It was like Christmas - every new piece that I looked at was interesting and exciting (even the few 2-1/2" squares and strange, crumby offcuts). I got a couple of larger pieces (1 yard or more) but honestly, it was the smaller pieces that were the most fun for me!
Don't forget to think about what would be best for you, as well. If it would be easier for you to just pop scraps in a tote and let people search through them, then do that. If it makes you happy to handle the scraps and sort them by colour or theme, then do that. Downsizing can be challenging so make sure you are catering to your needs while you are doing it. Good luck!
