Claws =/= unarmed strike.
Finesse Training is actually two abilities. The first thing it does is give you the feat weapon finesse as a bonus feat. The second thing it does is to allow you to choose one type of weapon that can be used with weapon finesse and add your DEX modifier to damage instead of your STR modifier. One thing to keep in mind is that you don’t gain the ability to even choose the weapon until you have 3 levels of unchained rogue.
The feat weapon finesse applies to any weapon that specifies it can be used with weapon finesse. This includes all light weapons, rapiers, whips and spiked chain. Since both claws and unarmed strikes are considered light weapons, you can use your DEX bonus to hit with either of them. However claws and unarmed strikes are not the same weapon so the DEX to damage portion of Finesse Training only applies one of them. This is of course assuming you take 3 levels of unchained rogue. If you are only taking one or two levels you don’t gain the ability to add DEX to damage.
Considering dragon disciple means you are already losing 3 caster levels taking that many levels of unchained rogue is not really a good idea. If you take 2 levels of sorcerer and 3 levels of unchained rouge before going into dragon disciple at 6th level, your caster level is going to be 2. You are going to be casting 1st level spells and doing very little damage with them. A straight sorcerer would be casting 3rd level spells at this point and doing considerably more damage with his spell.
I am not sure what your reason for picking up the levels with unchained rogue are, but it is probably going to weaken your character considerably.
So if you had claws at 3rd level you could name them.
You don't even need to have claws, you can simply name any finessable weapon you like.
i ran the character through both pathfinder kingmaker and pathfinder wotr, in both games the claws and hands were the same slot thus same weapon. as you have to have 2 empty hands to gain claws from the draconic bloodline.
Computer game rules =/= tabletop rules

You mean the video games? Haven't palyed them, but ion any case, they do not make rules for the regular P&P RPG.
I have no idea what you mean with "slot", but unarmed strikes and natural weapons are completely, 100% seperate.
as you have to have 2 empty hands to gain claws from the draconic bloodline.
Not only are unarmed strikes not tied to hands, you do not need "2 empty hands to gain claws from the draconic bloodline". You can't make attacks with hands used ofr other weapons (or for makign unarmed strikes), but e.g. a one-handed weapon and a claw attack with teh other hand would work just fine.
and it is hard to be in melee and threaten a space if you don't take improved unarmed strike no matter the class.
the issue is level 3 finesse training states chose a weapon but if you choose your unarmed strakes being the hands
Not a thing. If you chose unarmed strike you chose unarmed strike, not specific body parts.
us your free action to turn said hands to claws via the transformation rules the bonus would confer since the claws aren't permanent but are an effect on the hands.
What rules are you talking about?
Don't use the Pathfinder video games by Owlcat as an argument or or to try to understand nuanced parts of the rules. Owlcat makes changes for ease of implementing the rules into a computer game. It does not try to make a 100% rules accurate translation into a CRPG.
So forget everything you think if it came from the CRPGs.
