Don't have time for a full review tonight, but here's some bits to correct

Name: TR_CreamSandwich_Showcase
Clean: Yes
Lighting: Okay, but sunlight should be 1-20. 
Some lanterns are grouped close together, have them placed further apart of ensure the whole place is well lit. Use a 128 lamp somewhere too.
Northmarker: Present
Fits exterior: fits b_22
Pathgrid: Yellow path should be clear and not go through any statics. If a path is clear, there's no need for multiple nodes along it. The node infront of the door should go furhter towards the bookshelf.
Illegal to Sleep Here: Yes. Correct.
Gridsnap: 32. fine.
Bleeders: NOT COMPLETED
Floaters: NOT COMPLETED

Other:
Have the stairs face the upperfloor door (look at the TD hlaalu stairs too if they do the job better), this way you can place the bed in its own space rather than the hallway. This will also make the pathgrid less tight.

Remove the closet from downstairs, place one of the shelves there instead. A closet fits better in a bedroom, downstairs it only takes up space.

To save a reference, use in_hlaalu_hall_end rather than hall_corner + hlaalu_wall in the bookshelf room. 
Remove the guarscreen - it only makes things cramped.

You don't need the in_hlaalu_room_post downstairs (and in parts upstairs). When making hallways, use the hlaalu hall set.
There is a similar issue upstairs where you have used the room_door piece and have to use a seperate wall piece
Rugs should be bled down so the tassles are on the floor. Pillows should also be bled down.

de_p_chest_02_empty - furniture shouldn't be part on/part off a rug unless you tilt it (a lot easier to just have it on or off)

Tapestries should have their post bled into the plaster above the wood bar (without the rope bleeding)

Have a read of this document, which covers some of the issues eg: "One of the most common ways to unnecessarily increase the reference-count of a Hlaalu interior is by mistakenly using in_hlaalu_room pieces instead of in_hlaalu_hall pieces. The room pieces should be used when creating a room area without pillars. If you want pillars, use the hall pieces so that each pillar doesn't have to be a separate reference. The vanilla posts (in_hlaalu_room_post) should only be used when it’s not possible to create pillars via hall pieces (such as on the ground level in large rooms)."

Name: TR_CreamSandwich_Showcase
Clean: Yes
Lighting: Fine
Light_De_Lantern_06A - too bright 
Northmarker: Present
Fits exterior: Yes
Pathgrid: Generally fine. Node at top of staircase should rest on floor (would likely still function fine, but this is a standard)
Illegal to Sleep Here: Yes. Correct.
Gridsnap: Yes. 

Bleeders: 
bk_guide_to_vvardenfell
light_de_lantern_03_128 - all
misc_de_bowl_glass_peach_01 - needs to bleed more evenly, pointy end shouldn't be visble below rim
misc_de_bowl_redware_01 - also needs to bleed more evenly 
T_IngFood_EggMolecrab_01

Floaters:
food_kwama_egg_01; food_kwama_egg_02 - should be tilted so balances correctly 
furn_de_p_chair_02
furn_de_rope_03 x2
light_de_candle_03_64
misc_com_wood_fork 
misc_com_wood_spoon_01

misc_de_pot_glass_peach_01 needs tilt
Misc_Inkwell
Misc_Quill
sc_paper plain
potion_comberry_wine_01 on table
T_De_PeachGlassCup_01 needs tilt

Other:

the in_hlaalu_hall_3way + wall upstairs is not needed. the two can be swapped for 1 in_hlaalu_hall_center

ideally make flush with book next to it, or bookend

Swap the closet for drawers - this will make the area less cramped looking

Add some kind of clutter by the bed, eg a stool with an item on it

add a few more tapestries (same style is fine) through the interior 

add something to the corner at the bottom of the staircase, eg a container or lamp

Pathgrid:  Node at top of staircase should rest on floor (would likely still function fine, but this is a standard)
Bleeders: 
light_de_lantern_03_128 - top of stairs (match it with how you've done the others)
misc_de_bowl_glass_peach_01 - needs to bleed more evenly, pointy end shouldn't be visble below rim

Other:

Swap the drawers at the bottom of the staircase for something smaller - eg an urn or lamp
the occupant currently has no clothes, find/replace the chest or drawers with a variant that has clothes

Name: TR_CreamSandwich_Showcase
Clean: yes
Lighting: Sunlight values too bright, should be in between 10 - 25, fog is good, ambient could be a bit brighter
Northmarker: good
Fits exterior: no - discussed on discord
Pathgrid: good
Illegal to Sleep Here: yes, correct
Gridsnap: good

Bleeders:
- Furn_de_tapestry_05 (rope can’t bleed)
- misc_com_wood_spoon_01
- steel axe (top of head)
- T_IngFood_MeatKagouti_01 (just a tad too much bleed)
 

Floaters:
- De_p_chest_02_empty
- Furn_de_p_chair_02 (both need an F)
- Ingred_bc_ampoule_pod
- Ingred_bc_coda_flower
- Ingred_scrib_jerky_01 (both need an F)
- Misc_com_broom_01 (handle needs to rest on wall and head needs to sink a tad - into the bucket)
- Misc_com_wood_fork
- misc_com_wood_knife
- steel axe (bottom and head)
- T_De_Chitin_Longsword_01
 

Other:
- Misc_SoulGem_Lesser should be resting on one of it’s flat sides (try looking at wireframe view to see this clearer)
- would recommend using a flat TD version of de_p_closet_02_de_mclot to make your life easier placing objects on top
- T_De_Drink_BourbonGoya_01 is a rare, high class Hlaalu drink, is generally reserved for rich interiors. Recommend swapping out with one of the more common local drinks.
- Shelf downstairs could use a tad more clutter
