I don't know how to choose whether to be an electrician in the property or a general worker in the factory.

Let's prioritize. Since you are in debt and want to make money, of course, you must go to the factory first. I don't want to wait in the factory for a long time, until the debt is almost paid off before changing jobs. The electrician's night shift is not ideal. Not many people take intravenous drip in the morning on weekdays. The other one wants to rent a car. If he has a car, he must pay for the gas. If he doesn't refuel, he has to recharge. So do the general work first. Good wishes!
