- Ask for: Discount... (a discount for the station unless NPC is a Trader, than you could chose a discount with them instead).
- -not used-
- Ask about: Job applicant ** (offers the location and skills of an NPC of a chosen type with the best, unknown skills, on their station's platform).
- Trade Updates (see below as not all NPCS offer it; they unlock continuous, real-time market info for the NPC's station).
- Give: Item... (craftable gift that unlocks level 2 of smalltalk).

* A score of 7+ or more across 2 or more minigames that include no critical failures) ** I think these options can only point to NPCs with unknown skills so there could be other NPCs available to hire within range that won't be highlighted if their skills are already known. It makes sense to use these options where there are a lot of NPCs of the type you are interested in (e.g. see sidebar for zone, or station dock menu to check platforms or station population).
*** A score or 4+ on each of 3 minigames.
Trade UpdatesAgents
These will only be offered by a subset of NPCs.
NPCs that can offer Trade Updates:
Arms Dealer
Inventory item traders (e.g. Food Merchant or Black Marketeer).
License broker
Mechanic
Recruitment Officer
Ship Dealer
Non-hirable station crew, which are working on a station (Defense Officer, Engineer, Manager or Specialists) - typically found on Administration platforms. By "working", I mean generally hanging around in bunk rooms chattering with random passers by 
NPCs that never offer Trade Updates:
Architect (even if they are working on plot-rated NPC CVs)
Captain
Marine Officer
Pilot
Station crew if they are available for hire (Defense Officer, Engineer, Manager or Specialist).
Discounts for stations or traders
A smalltalking NPC can offer a discount at their station, which offers higher profit margins if taken advantage of. If smalltalking with an NPC Trader (e.g. Blackmarketeer, Arms Dealer or Mechanic; maybe Recruitment Officers too), they will offer a choice of station or personal discounts. Station discounts from smalltalk apply on top of any other discounts, such as via Standings or those found outside stations while flying around nearby. Therefore they can all be stacked up to gain a higher profit margin than would otherwise be available.
Location and skill visibility for hirable, well-skilled NPCs
I think these options can only point to NPCs with unknown skills so there could be other NPCs available to hire within range that won't be highlighted if their skills are already known. It makes sense to use these options where there are a lot of NPCs of the type you are interested in (e.g. see sidebar for zone, or station dock menu to check platforms or station population).
Collecting Training Manuals
These are only available via the craftable gift option after the first smalltalk and if the second smalltalk was completed with a score of 9 or 10 points. Good completion of the second smalltalk allows us to ask for 'Training Manuals', which are unique to Smalltalk. They are available for various potentially important skills, such as Engineering, Leadership and Morale. A Training Manual can be used to add one star to the related skill of one of your hired NPC's primary, bold-highlighted skills (e.g. only Engineering for Engineers), to a maximum of 5 stars. Exactly which Training Manual you may be offered relates to the primary skills of the NPC in question so it is somewhat random in the sense that it is random as to which NPC may begin a smalltalk.
