As far as your specific question, Most of it will, some of it won’t.
First things first, what country are you in? The device selection does vary somewhat.
Also, although there is a SmartThings version for Nvidia, you can’t add that to any other SmartThings network. So you would use either the Nvidia version or a regular smartthings hub. Not both. But then you wouldn’t need both.
As far as the smoke sensor, smartthings only works with the older battery operated Fibaro model, not the one you linked to. But you might want to wait on selecting that until you know what security system you are going to have.
You have zigbee sensors on your list, but no zigbee repeaters except the Aqara switches, which don’t work well with SmartThings. Read post 11 in the following FAQ, then go up to the top of the thread and read that whole thread and you’ll understand much better what this requirement is. (The topic title is a clickable link)
There is no official nest integration with SmartThings, but there is a custom integration which is very popular.
Smartthings’ integration with any camera is very limited, and may not be what you are expecting. So I would look into that carefully before making those decisions.
Also, you may have already seen this, but I would suggest reading it as well:
