Seems like a genuine concern voiced with a tone of frustration, using this thread as “inspiration.”
I agree that for a new user it is difficult to know what is in the realm of achievable, with or without community plugins.
I also agree it would be difficult/impossible (imprudent?) to make an official docs page on how to do this and that using this and that third-party plugin.
So one needs to read and bookmark forum threads, watch videos and brainstorm, try out stuff in test vaults, etc.
