I see the question asked a lot in Linux groups, so I hope this bit of knowledge may help someone here.

Thank you, that’s an important distinction to make.
A digitized handwritten signature is not a digital signature. The latter is valid and enforced in court in some countries, the former is worthless.
I’ve found Xournal++ is good for markup as well

Good to know that you can digitally sign PDFs in LO Draw, thanks!
Inkscape is decent for basic PDF editing as well, though depending on the font the textboxes can end up mangled when you edit them. The import is supposed to me even better in version 1.3, but I haven’t had a chance to try it
Just use GIMP. It can do multiple pages of pdf too.
But can it edit text fields ? like not drawing over them but changing the actual text stored
LO Draw has trouble with editing if PDF has fonts that aren’t installed system wide. They are auto-replaced with another font and texts with unknown fonts may move slightly compared to original document.
How good is it? Say I have a textbook and the errata, can I manually copy the updates from the eratta to the textbook without loosing the chapter markers?
