Is the 3M one the more common one I see on states like TN or NJ? Or is it the other one? Just wondering.
Tennessee and New Jersey do not use that generic 3M font characteristic for flat plates, but instead use more legible fonts. The same applies in Alabama, Arizona, Delaware, Georgia, Montana, South Dakota, etc.
What I'm meaning about the "3M font" is an artificially condensed variant of some Zurich Extra Condensed font first seen on flat plates and used since at least the early 2000s, nowadays in Washington, DC, Idaho, Indiana, Iowa, Texas and Wyoming (+ plausibly Ohio since Dec 29, 2021), as shown below:

It looks like that Kentucky uses it but it does NOT; a completely custom font apparently made by Avery is used instead.
