by all means use the highest rating caps you can get..BUT the larger voltage rated caps also use a bigger case size and can sometimes be a challenge to fit into the converter enclosure..the 440v rated caps seem to be a good tradeoff between case size and voltage rating..my shop converter has 440v rated run caps and has been going strong for an easy 25yrs.The starts usually are closer to max with a 330v rating.

I feel like a dummy.

I had wired my vfd up wrong and that's why it wouldn't run the mill.

I thought the yellow wire was a motor lead. It's a wire that runs from the stop/start buttons on my Kearney & Trecker

Wow, a Three Star Cutler-Hammer starter, that’s at least 50 years old, likely even more with the wrapped coil.
