Another place #6 NM is a real problem is with EV car chargers. Tesla's car charger has a setting of "Maximum Current Output of 48A and Circuit Breaker 60A". This is a situation where #6 romex is no good, but #6 MC is fine.

Not familiar enough with the application, but would say unless NEC specifies this is a continuous load somewhere it is probably acceptable to use 60C conductor for this.

That is a good example of where you cannot use the next standard size up rule.
