Wire
I love wire. Wire is one of the Modular Electronics.
Tips/Techniques
Buy in Bulk
You will save a lot of money.
Look for Local Surplus of Wire
I found 2000 feet of 22 gauge wire for $15 2024 prices from a local electronics recycler. Wire is one of those things that the wire factories can't stop breeding producing, so there is always a lot around.
Wire Wrap
Not a lot of modern use of wire wrap, but the small gauge wire and the cutters are useful. Pretty much if you build a board with wire wrap, murphy will disconnect/cause oxidation on three wires and you'll never figure out why the board doesn't work.

Compare speed wire to wire wrap. The former is a lot more reasonable, but you will still need an enclosure otherwise wires will get knocked off over time.

Soldering Wire to a Bolt
Assuming you match the metals correctly: https://www.eevblog.com/forum/projects/how-to-reliably-connect-copper-wire-to-stainless-steel-bolts/msg5446019 Solder lugs are cheap. I bought a few for a Spot Welder I made.
IDC Cable Problems
https://www.eevblog.com/forum/projects/high-reliability-ribbon-cables/msg5449421/ - Digikey made cables error. No one bothered to look up the cable (they kept asking: "who makes it?") until the 2nd page, even though info was provided.
