Good morning:
It's really, really difficult to find one firearm (of whatever type or classification) that can 'do it all' no matter how much one has to spend. When trying to buy 'something to do everything' the law of averages dictates that what you'll end up with will be 'average' at best for whichever purpose you try to use it for.
My recommendation is this: decide what you want to do most/first/foremost. Buy what fits that requirement. If that is not possible try to place the most emphasis on what you expect to do most ie. "I want a cool removeable magazine black rifle that I can compete with but can take a deer with if I have to," "I dig 'actual issued' milsurp most of all but want to try and enter some competitions too," etc. Once you've ranked your priorities from 'most' to 'least' important, buy accordingly.
This way at worst you end up with something that will still be great for what you do or like most and won't become a fifth wheel when - like most of us - you acquire more than one long gun.
Hope this helps,
- Peter
P.S.: VZ-58S carbines have started appearing on the firing line at various matches but I am not a competitor so I'll leave it to those who have competed with one to share their views.
