Hi Paulo,
I am guessing you were ~4m far from wall when taking photos. In my exterior house example, I made mistake when I was too far(9m) from plaster wall. When the distance was 2.5m, I got perfect result(small plaster details captured in pointcloud) on walls. Your interior plaster does not have the amount of details like exterior, so you need to go closer to wall and from that reason make a change in the way of photographing the interior.
In handleWalls image I am making also oblique angles from the same photographic point(red dot is position, blue line direction). This helps to keep continuity with less moving of the tripod and also it helps reduce spikes on flat surfaces(because from perpendicular direction it is hard to tell how far is something from camera,...it is much easier from side angles).
In handleCorners I hinted how to keep continuity between walls.
HandleFurniture picture is obvious, it is simple rock photogrammetry scenario.
My workflow will create overall higher number of photos, but it potentialy has some benefits: you can try take photos from hand, with higher ISO(and keep 1/60 to avoid motion from hand), because you will be much closer to walls/objects and their details can beat the ISO noise. You can finish photoshooting sooner, because changing tripod positions can be very anoying.
You can try also switch the ceiling light on for adding some light and shadow details on plaster when shooting walls and corners.
I hinted just 3 directions from one red dot, but you will need also few up and down directions to cover all surface area.
Let us know if this kind of aproach make your result better, or thetraditional aproach is better for interior.
