Hello @mreckert, welcome to the forum!
Based on the information you provided, these are the best options I could find on offer for those descriptions:
AWG14: https://www.digikey.com/short/dmf7f3vv
AWG16: https://www.digikey.com/short/dw0nhm79
AWG12: 5879/12WH001-ND
Each of those lines links to a list of parts that seem reasonable matches to your description, exception being the 12AWG wire, for which I only found one option. Comparing the options, it’s not clear that these will perfectly match the specifications you’re looking for, so I recommend reviewing them to see if they will work for you.
