There are 2 scripts at work.
First creates attachment – text file - in data driven pages polygon stored in FGDB, name in TOC = Pages.
Data sourced into attachment table from layer called ‘pnts’, it has to have page definition query active.
To control appearance of future table you’ll need text element in your layout called TABLE.
This is what tool expects as parameters:
The values in field list are field names from ‘pnts’ that you want to show:
Yes you have to change list to suit you needs.
Script iterates through pages and does:
- Remove existing attachment
Create attachment from values taken from pnts table within current
DDP.
(I usually create a small buffer around pages, intersect it with pnts. This create 2 pnts where buffers overlaps)
I use is Calibri Light font for text in the TABLE.

Output example I am using to control how prints will look like:
Note grey part is separate element here. You also have to change text format line in above script.
Second script does printing (export to pdf, using DDP name), assumes DDP layer name = Pages (the one with attachmet) and there is text element called TABLE in the layout

env.overwriteoutput=True
folder=arcpy.GetParameterAsText(0)

result=layers[0]
return result
mxd = arcpy.mapping.MapDocument("CURRENT")

diction={}
both=arcpy.da.TableToNumPyArray(thePagesLayer, (fld,"OBJECTID"))

query='REL_OBJECTID = %s' %str(int(OID))
with arcpy.da.SearchCursor(aTable,'DATA',query) as cursor:
for row in cursor:
binaryRep = row[0]
textB=binaryRep.tobytes()
if len(textB)>0:
tableTxt.text = textB
else:
tableTxt.text = " "
tableTxt.elementPositionY=y
arcpy.RefreshActiveView()
ddp.exportToPDF(folder+os.sep + baseName + ".pdf","CURRENT")
arcpy.AddMessage('Exported %i %s' %(pageID,baseName))
except:
message = "\n*** PYTHON ERRORS *** "; showPyMessage()
message = "Python Traceback Info: " + traceback.format_tb(sys.exc_info()[2])[0]; showPyMessage()
message = "Python Error Info: " + str(sys.exc_type)+ ": " + str(sys.exc_value) + "\n"; showPyMessage()
In above example points are labelled by SectionID and table provides perfect reference.
This couple saved me weeks of time...
I am using 2 scripts because formatting is a hard part, so I run first script with only 2 layers - points and pages on a very basic mxd. Second works fine and I run it on the map with multiple layers, symbology sorted etc
This is an upper right corner of one of the output pages:

and for label position (horizontal alignment) :
CASE
WHEN "auxiliary_storage_labeling_positionx" < $x THEN 'right'
ELSE 'left'
END
Best Answer
On the 'Advanced' tab of the 'Layer Labeling settings' menu there is the 'Engine setting' button. If you open that dialogue, you will see the option to show all labels, including colliding labels. That should give you more control and a more consistent behavior.
Something I used to do previously when I had similar problems with label placements is to create centroids of the polygons (vector - geometry tools), label those using the option to label over point and then move the points around to ensure perfect placement of your labels.
