The more you understand SVG, the less software you need to create it.
I just produced some logo deliverables by coding them directly by hand, and the result is much so better and cleaner than all my previous attempts in Inkscape (a disaster) or Penpot (much better but still not good enough).
To export them as PNGs, I simply display them on a web page and use the browser's screenshot function. It works really well and is incredibly satisfying.
