The answer is, there is no way to really know. There aren't enough details above to tell you.
By default, building Apps based on data is one thing, building it with flows that do everything you need etc in a single swipe, no its not there yet, not really. that being said.
No, there isn't any direct way to just get an MSApp back either, there are no full-fledged build everything and get it right, also there isn't a way for it to tell you what it "couldn't do" so that you can finish it up.
The best you can really do is Build a Plan and try to execute the Plan and see what it can do OR
Build the lists first
Then build the App based on the lists (using Copilot)
Then go into Power Automate and build the flows based off what you need it to do using (Copilot)
then connect them together.
You might be able to get away with on of those 2 options as getting you as close as possible but it will still take step by step from yourself to really get there.
I wish there was a 1 and done, but its not there yet.
