Fastest external RAM and Flash for STM32H743II


I want to know which external RAM and Flash is the best option for STM32H743II which you used and had good results?
This project is for the university, so they pay for it.

And when I want to use other ST microcontrollers, which microcontrollers and which external RAM and Flash are the best options for them? When you used them, I can be sure that those ones work for me, too.

We need also to have an acceptable speed on our device. So, you know which external RAM, external Flash, microcontrollers etc. work better.
And the board of the microcontroller must be small like the one which I have. I have an OpenMV Cam H7 Plus which has an acceptable board in terms of its size.
