STM32 Self reset

Is there a way to self reset other than watchdog?

Without external pull-up resistance

I want to keep the GPIO high even if the MCU performs a soft reset.

Is there any way?

Call NVIC_SystemReset() for software reset, but no reset will retain the pins settings in GPIO, including pull-ups.

Yes, please read the reference manual of the respective device for the section Power Reset, which contains all sources for the internal reset.
