A few ideas:
-- I got 2x tackle boxes to store / organize my cables in. In practice these are okay not great for modular cords, because the inner box divisions are somewhat small and can't be changed. I might try getting some bigger tackle boxes (or at least ones with bigger compartments) and repurpose the ones I have. The ones I have which work okay are: https://www.amazon.com/gp/product/B07R5SLQCW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
-- if I wanted a more permanent cable setup (e.g. one I don't mind staying out in view) I would probably get one of these, which goes on top of a mic stand: https://patchwerks.com/collections/cable-hangers/products/eurodesk-z-hex-01-eurorack-1-8-inch-cable-hanger. Also there is a wall / deskmount option: https://www.eurodesk-z.com/products/klauz1e-wall-mountable-1-8-inch-eurorack-cable-hanger
-- for cables, I like the Ad Infinitum cables, which you can get direct or via retailers (may as well go direct, IMO): http://adinfinitummusic.com/. I like those because i) they seem to have a good reputation for build quality and my experience is good with them on quality ii) they have enough colors and sizes for me (I want all black in a number of sizes). Regarding # of cables I would say i) consider the longest cable length you would need given your setup ii) get a few lengths from smallest usable to medium to longest usable iii) get at least 5x of each length. For me, I got 15x cables in 6,12,18,24 &36 and that's about all I need for now. IMO for $50-70 you should be able to get a good set of cables which will cover a wide range of your immediate patching needs.
Good luck!
