For font and alignment you could check out our FormMagic add-on: http://www.id-extras.com/products/formmagic
For text box stroke, I'm not seeing any problem with this carrying through from InDesign -- when I set the stroke of the text box in InDesign CC2015, and then convert that text box to a text field in InDesign, and export to interactive PDF, it carries through to Acrobat with the stroke intact.
The issue of file size probably can't be helped, though you could try to see if FormMagic creates smaller size (just remember to use the Purge FormMagic data in Acrobat first!)
Are you talking about the form fields?
Yes, the form fields.
I create the form in InDesign that includes several named "text" fields - export to Acrobat and then the fields get populated by a script based on field names.
