Yes, MCPWM. I assume that your fake H-bridge is intended to do PWM-like things in a push-pull configuration? Then you want a peripheral like MCPWM anyway. If not your use case is probably so slow that you can set and clear the two GPIOs in software anyway.
(Also, note that whatever you have in mind ...

Re: Powering an ESP32 S3 Zero..
First of all, you probably want to keep R8 from your original schematic, as well as flip D4 around.
Second of all, you cannot fulfill the requirement that the internal 3v3 cannot feed the external 3v3 with that schematic, as the body diode of the mosfet will allow current through that way.

Re: ESP32-C5 devout fails to flash
You're probably using a version of the chip that is not supported by the ESP-IDF version... maybe you can try the master branch?

Re: SD Card write -> swapped blocks
Are you making sure that there is absolutely 100% no way the second core can be writing to a buffer while the first one is reading from it? Asking because I don't see any inter-task communication methods used.

Re: random hardware reset
It's odd for sure. Do you have more boards like these, and do they have similar issues?

Do you normally have anything connected to j2?

Re: Issue with receiving of Serial Data
What color is D6? (And yes, this is relevant.)

Re: Powering an ESP32 S3 Zero..
That won't work. Q8 is a P-channel mosfet, so it allows 3.3V through when its gate is at ground level. Meanwhile, Q7 will ground that gate when 5V is applied; so you're getting the exact opposite behavior compared to what you intended. You probably want to remove Q7 and connect D4 directly to the ...

Re: Very strange LoadProhibited crash
Are you sure you're doing re-entrancy properly, as in, do you use proper mutexes/semaphores/queues/... to move information between tasks rather than simply updating variables the other task may be using at that exact moment?

Re: GPIO pins in differential mode
You can, if you use a peripheral to control the motor. Use the driver to route your positive signal as normal. Use the GPIO matrix to create an additional inverted signal for the same source.
