For using an Arduino, would the programming required be feasible for a non-CS major engineering student? I have some programming experience but nothing super in depth, but if it were feasible I would definitely be willing to learn the required programming.
The link I showed had a video showing how to do it in LabVIEW. You don't need to program the Arduino at all, you just use the premade LabVIEW functions to ask the Arduino to return, or output some data. But again only if the range and precision you need is adequate which it might not be.

The load cell I am planning on using: PCB Piezotronics Model 208C05
The signal conditioner I am planning on using: PCB Piezotronics Model 482A21
For precision, I would prefer if the DAQ would read to one decimal point, any more precision is unnecessary (although the more precise the better). I am unsure what exactly is meant by range, but the load cell will be reading forces between 1N and 10kN.
Thanks for all of the help

So your sensor outputs 1mV/lb. At its maximum rating it will output 8V.
For a max 10kN load, it will output 2.2482 V. The gain of your signal conditioner is 1:1, so it will not add anything to the signal.
So if you stay within 10kN, your range needs to be at least 2.3V.
If you have a +/-5V digitzer with 16 bit resolution, your resolution is about 153uV, 12 bits 2.4 mV.
