Like others here, I make my own. I haven't bought pre-made lead in over 20 years.

I've been using Van Damme cable for about 6 years now. It's low capacitance (27pf/ft) and very flexible with low memory.
I always add heat shrink for strain relief, and with good quality plugs, can make a 5m lead for under $20AU.

For my pedalboards, I do use Lava solder-less plugs and their Tightrope cable. That's the closest I come to manufactured leads though.
