Creating editable/fillable pdf in indesign

this has been very helpful. thank you. the only other barrier I've stumbled across is once the form is ready to be filled out - it defaults to times new roman when typing in the text field. Is there a way I can select the font id like used for filling out the text fields?

As Derek rightly pointed out, to make entries in your form fields, your form users wouldn't need Acrobat; only the freely available Adobe Reader​.

...this has restrictions on who can then edit the file - only people with adobe acrobat can.

It depends on what you mean by "edit." If the editing need goes beyond making entries in form fields, then you're correct, Acrobat Pro is required; and that goes for any PDF (or PDF form), regardless of whether you compose it in InDesign, Acrobat, or a combination of both.
