We are using STM32G041F8P6 MCU.

Should we assert NRST reset after power on of STM32 or

should we hold hold reset signal of STM32 during power up (any Power on Reset circuitry required)?

Please let us know

You only need the power-on reset, an additional pulse to NRST is not required. Details for the STM32G041 can be found in RM0444, sections 4.2 and 5.

Does it answer your question?
