I've been looking through ClientFullBuild0.package and found a few interesting things. First of all, the tag "DATA" is related to any values relating to careers, achievements, moods, and anything else you might want to tune.

Second of all, everything is organized by resource group. Using S4PE, this is what you can expect to find in each resource group from ClientFullBuild0:

1. Aspiration Track - 0x0020FC6D
2. Situation Job - 0x000785C3
3. Mood - 0x007B6002
4. Buffs - 0x0017E8F6
5. AchievementReward - 0x00334E67
6. RelationshipBit (different situations in relationship) - 0x004DFB84
7. Aspiration Category - 0x0050DB3B
8. Achievement Category - 0x0051C125
9. Achievement - 0x00559EE6
10. Career Situation - 0x0059C569
11. Trait (**This includes walk styles and other personal things**) - 0x005FDD0C
12. Objective - 0x0069453E
13. CareerLevel - 0x0070ADD4
14. Client_Tutorial - 0x0073074B
15. Mood (again) - 0x007B6002
16. Global highlight settings (Renderer) - 0x007E2E29
17. Career - 0x00996B98
18. Commodities (buffs, needs, etc.) - 0x009BC58E
19. Rewards (household & sim) - 0x00A49847
20. Global light settings (Renderer) - 0x00B2600F
21. TutorialTip - 0x00B3E03E
22. AspirationSimInfoPanel - 0x00B6465D
23. Venue (types of venues, it seems) - 0x00BBD738
24. TunableCareerTrack - 0x00C75CAB
25. Pie Menus - 0x00E9D967
26. ScreenSlam (perhaps something like what happens when you get a gold medal at a prestige event; after it's over, it "slams" your screen with an enormous medal) - 0x545AC67A
27. Subroot - 0x00FF8F22

I hope this makes everything just a little bit easier!

Thanks! I haven't had much time to take a closer look at the Sims 4 packages, so I really appreciate having a jumping off point of sorts for exploring them further.

Here's a more complete list that I created when I first analyzed the DATA resources. For everyone trying to change tunings, please note that they often have an xml counterpart that also needs to be changed. The EA modding documentation gives more information on that and includes files with descriptions for the various settings in the tunings.

0x0003C397 = ColorFiltering, BuildBuy, ObjectTooltip
0x00057D11 = Tags/Filters
0x000785C3 = SituationJob
0x000A3610 = CAS_LightingTuning
0x0012D444 = Client_TagCategoriesMetadata
0x0016353A = SlotTypeSet
0x0017E8F6 = Buff

0x00496642 = Client_CASThumbnailCamera
0x004A2443 = Tutorial
0x004B5265 = Client_CAS(Camera)Tuning
0x004DFB84 = RelationshipBit

0x0070ADD4 = CareerLevel
0x0073074B = Client_Tutorial
0x007B6002 = Mood
0x007E2E29 = Renderer.GlobalHighlightSettings
0x008811FE = Video.GlobalTuning
0x0094E9AE = NativeBuildBuy
0x00996B98 = Career
0x009BC58E = Commodity/Statistic/RelationshipTrack
0x00A49847 = SimReward/HouseholdReward
0x00ABFFCF = Client_CASModifier(Tuning and other stuff)
0x00B2600F = Renderer.GlobalLightSettings
0x00B3E03E = TutorialTip(Group)
0x00B6465D = Aspiration(SimInfoPanel/Career)
0x00B98960 = Client_TagsMetadata

0x00D2B461 = AchievementCollection
0x00D6FA33 = Renderer.CensorTuning
0x00DB5F47 = CAS.SimLightingParamsWorldData
0x00E2451B = Renderer.GlobalVolLightScatteringSettings
0x00E5D42A = Telemetry.Tuning
0x00E9D967 = PieMenuCategory
0x00F216E1 = ScreenSlam
0x00FC90DD = Renderer.HsvTweakerSettings
0x00FF8F22 = subroot

Great list!

0x009BC58E = Commodity/Statistic/RelationshipTrack

Just noticed this also contains skill data (instance 0x0000000000004113, for example).

ETA: I still can't seem to find data regarding Hunger/Fun/any other motive. I think it may require very exhaustive searching :D

S4_545AC67A_009BC58E_0000000000004110 is the hunger motive. And yes, 0x009BC58E seems to be a catch-all for all kinds of statistics tunings, e.g. it also includes job performance.

I'm moving this to Modding Discussion since it's not a tutorial (actual instructions). I linked it in "Resources" in the Tools/Docs/Resources sticky though, hopefully that makes sense =).
