NB There's some mixed reviews when it comes to noise rejection with the EBS-type of flat cable.
Another option is the Ibanez mini link series. Not only are they small, but their sound/noise rejection is very good. There's a YouTuber who did a kind "scientific" test of many patch cables, with a giant spreadsheet as output, and the Ibanez came out pretty much on top. If you search you'll find mention of it.
And luckily, the same product seems to be sold by Harley Benton for cheap: https://www.thomann.de/gb/harley_benton_solder_free_patch_cable_kit.htm
Downside is they are not robust.
If you can solder, making up your own cables using the Squareplug SP series ends up being only a couple of mm less slim than the EBS etc. And the quality is excellent.
