Sources for wiring supplies? (LED Cargo Light Project)

I'm planning some LED strip lighting for my RSI Smartcap and haven't found a packaged solution that will do what I'm looking to do. I'd like to put in a couple zones of lighting in the main cap and on the doors. I'll run power back to the bed and put in a box for switches somewhere near the tailgate.

Where do you all like to buy your switches, terminal blocks, fuses and such supplies? Preferred manufacturers? I'd like to try and source some reasonable quality parts and not buy common junk I find on Amazon. I don't think I need to go fancy with something like Switch-Pros, but something of OEM quality would do, I think.

Thanks!

As usual, this forum saves me so much time. He even has a kit for the RSI cap. I think this will be a good place to start.
