I suggest you make a copy of the InDesign print version where the PPI is important and which should include bleeds and crop marks etc and make another copy of the document for your digital version.
I suggest you select PDF/X-4 for the print version and Interactive PDF for the digital version.
You can include things like internal and external live hyperlinks in the digital version and reduce the sizes of the images.
In Acrobat you can experiment with Save As Other > Reduced Size PDF.
