You need some degree of anti-aliasing otherwise the graphic will look horrible. It would be nice if you could turn anti-aliasing off for straight edge characters 'H' or 'L' and on for rounded or angled characters 'C' or 'A' but you can not.
I can see more anti-aliasing in your screenshot than I get with a Gimp 2.10.6 (linux) default jpeg. Not a lot, just some extra semi-transparent pixels.

Could be an OSX issue.
Companies like VistaPrint love PDF so that is a good way to go. The best (free) tool for creating a PDF for publishing is Scribus.
Why will they not accept your PDF? Could be an embedded font. I converted the text in the svg to a path because the probability is you do not have that specific font.
Why will they not accept your PNG? a black and white png by default is a color-indexed image, maybe that is the problem. Not the most wonderful company for proving information.
edit:
Gimp is a raster (bitmap) editor and works in pixels, not centimetres or inches. Only when you come to print does the resolution come into play and you can check the print size in Image -> Print Size For quality printing the generally accepted minimum is 300 pixels-per-inch (ppi), but that value depends, biz card 300 ppi, an A3 poster maybe 150 ppi.
A PDF will scale up or down providing the contents are vector. Embed a poor quality bitmap in a PDF and there is no fix. Gimp produced PDF is a bitmap so make sure it is good quality.
Be careful opening a PDF in Gimp. The default conversion is 100 ppi increase this to 300 ppi for editing.

Quote:The thing that probably confuses me is when I open the jpeg, it shows the actual size in pixels and NOT the actual print size like the pdf does
