2nd this. It is by no means a "PDF Editor", but it works surprisingly better than most.
Inkscape also could be a good option in OP's case because it gives options about janking up text. It can either try to find the fonts from those on your system, or it can change every glyph into a path.
That being said, I've treid both Inkscape and LO Draw, and I've had more luck with Inkscape in regards to keeping fonts similar. In 90% of cases (and I do have to fix up PDFs every now and then) the "Keep text" option doesn't jank up text.
