12 or 24V Motors? , from Trucks or Cars?

Hello to the entire community. I have finally managed to put together the pieces of the puzzle, I have the desire to do it, the software, the electronics and a couple of 12V motors used in windshield wipers, but "an existential doubt" has arisen...

Apart from the power supply, what difference is there between putting a 12V motor or a 24V motor... some have better performance?, some "suffer" less effort?, some will last longer running without overheating?
What do you suggest, 12V or 24V and why?

In addition, I have seen windshield wiper motors of all sizes, from those used in trucks (for example Mercedes Benz 1114) to cars (smaller in size and I do not know if they are strong enough) since there is a notable difference in prices between one and the other another type.

On the other hand, I have two 12V motors to test but different in size and even in revolutions. Does that have an influence - for example, if I want to do a test run or is the system itself responsible for regulating the movement independently of the rotation ratio provided by the gear reduction box?

Sorry if these are obvious questions, but I want to start and I think these are the main questions that the group's experts will be able to answer. Thank you very much for reading me!

My experience... Started to build up my rig with 12v windscreen motors(my 24v's where in transit)...
12v..works ok, but the controllers (in my case IBT-2's) getting hot quickly. (less V is more Amps)
Now with the 24v motors (pulled down power to 19v)... aswell the motor and IBT never get hotter than 40C..

OK Friend, thanks for your comment. Unfortunately, as I said, in my country everything is going up in price crazy due to the sad situation we are experiencing, what last week cost 1 U$D today costs 2.50 and the prices of engines have increased tremendously so I had to take the decision to make the purchase since I had no answers at the time of making it. It is good to know that the controllers raise temperatures, but I think that the Monsters that I have acquired have plenty of range to work (they are 30 Amps, the motor is around 2 to 3.5 Amps approximately from what I have managed to measure) and I can always add better dissipation and a corresponding ventilation system. On the other hand, a 24V motor would have forced me to buy a couple of extra power supplies since for 12V I have everything available at this moment.
I greatly appreciate your time and dedication in responding to me.
Warm greetings from the South of Argentina!

24v would be better and less hot.
The 2 motors need to be the same, if they are different it will be difficult to install.
The motor doesn't need to be too powerful if you balance the seat well

Thanks Qui. Unfortunately I couldn't get 24V motors at a good price, everything has gone up extraordinarily due to inflation. Finally I acquired two 12V Bosch 9390453086 and luckily the power supplies support them without problem. I will see the temperature issue when putting everything together, but I think it will be solved with a couple of suitable coolers. Thank you very much for your answer.
