Ok, not exactly clear what you're looking for

Getting a pretty simple STM32 board designed and functional shouldn't be that hard.

The Data Sheet does have a lot of detail.

Most people fail because they decide to skip basic things.

Do not wire up all supplies. Especially the Analogue one

Chose to leave off components and supplies they think are optional or inconvenient.

Don't connect BOOT0 to a pull-down.

Ignore VCAP pins and capacitors. Choosing random components, or nets.

If you follow sound design practices, the board should startup. Due diligence at the pin and netlist level is also important, go back to the original documents, not tables you've generated or had CubeMX generate along the way, basically close the circle. In IC design sending off a bad design is very expensive, so you check it a lot first, and then check it some more, and have others cross-check,

Adding more complicated external parts and interface, you're going to have to read more documentation. By "reference design" I'm assuming parts, driver sw, layout/signal path expectations. Across the STM32 boards and models there's a lot of working templates.

AdaFruit carries some of the Chinese board, though admittedly not the one you want

Seen boards on AliExpress

Couldn't you use NUCLEO H7A3 or EVAL/DISCO H7B3 as direct equivalents?

Yeah I saw that. Problem is 70-80 days to deliver. I have a NUCLEO H7A3 and you're probably right in that it is adequate. Along with the Altium files. I'm just always tripped up by subtle differences...

Thanks for your help

Also - I want to create a board with 4 layers max and as I recall all the dev boards produced by ST are 6 layers (or more?)
