I would really like the cargo area to remain up/open without having to manually hold it (or use a brace/stick )

Is there a way I can determine what is needed by determining how heavy the lifting board is?

Any other advice?

We added a pretty heavy mattress topper to our 2020 29RLKWE RV King and had to swap out the struts for beefier ones. I can't recall if/how I determined the weight rating on the originals, but purchased these 220 lb rated models and they work well.
