STM32F3 GPIO current sourcing question

Hi, I am using STM32F301. If I configure the GPIO pin to be output mode, and configure it to be open-drain with pull up, what would be the pin's current sourcing capability? What is the value of the internal pull-up resistor? If I need to use this pin to switch a MOSFET, is it better to configure it to be OD without pull up or pull down, and instead using an external pull up resistor?
