It probably doesn't even need a board, you can just wire all the sensors in a box and solder the cables. Each sensor only has 3 or 4 and so does the display.

But a board is cleaner and they're super cheap to get made in China unless you're shipping to the US I guess lol.

I've built sensor boards like these too. But more with Dallas one wire sensors to measure temperature in different locations of central heating systems.

Wires are chaotic and a point of failure

True but they do facilitate more flexible placement. I use them a lot for one off projects.

Have you tried kicad

No I usually use CircuitMaker. I like their big footprint database.
