Shameless plug: I built https://simplePDF.eu as I was similarly frustrated by the lack of a good PDF editor when filling French paperwork.

Checkboxes for example did not seem to be available in any of the tools I found.

I also figured that if I had to spend the time to position the fields, someone else shouldn’t spend that time too: crowd-edited PDF if you will (the document never sees my server)
