A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.

A 1/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 30 amps for 500 feet on a 240 volt system.
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
The wire size depends on how much current it will conduct.
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.

Use 8 gauge wire.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
For a 60 amp service: At 750 feet away, you would need at least #4 copper or #2 aluminum wire to account for voltage drop. At 500 feet away, you could use #6 copper or #4 aluminum wire for the same purpose.

Up to about 100 ft the size of the wire is determined by the max current and not the distance. A 90 amp supply needs #6 wire. <<>> A #2 copper conductor will limit the voltage drop to 3 percent or less when supplying 90 amps for 75 feet on a three phase 480 volt system.
