Advice on development kit selection for 7 or 10" display

Hello - I'm just getting started and would like to evaluate TouchGFX. I'm interested in developing for a 7 or 10" display and am trying to select an appropriate development kit. I've found these as options:

https://www.waveshare.com/product/mcu-tools/stm32/open/open746i-c-package-b.htm

Waveshare Open746-C with STM32F746IGT6 - This seems to have two display interfaces to handle both lower and higher resolution screens. Details are sketchy and I can't find what display interface is used for higher resolution screens. I don't think it supports MIPI DSI.

EDT ETEM070006XDH6 - A 7" display development kit available from EDT. Only available through the company who likely price it to find those that have an active project and are further along than I am.

32F769IDISCOVERY - ST development kit that can come with a 4" capacitive touch display. As far as I can tell it only has the MIPI DSI interface, but can support larger displays (although I don't know enough to determine whether its RAM and external flash will support larger displays).

Since there is a TouchGFX template for the 32F769IDISCOVERY, I'm thinking that's the best choice. I could learn using the example on the 4" display, then hopefully move to a larger display when I'm ready.

Are there any options that I've missed or anything else I should consider given that I know very little about TouchGFX and my experience with displays in general is dated? My goal is to evaluate TouchGFX for use on screens 7 to 10" for use in an industrial environment.

Thanks for any advice.

The RPi 7" display is on the edge of the DSI envelope. I've driven large panels with the DSI/HDMI adapter on the F769I-DISCO

Thanks for the reply. What is the DSI envelope?

Resolution vs bandwidth vs 2 lanes.​
