Creating PDF logos
For the last 20 odd years I've saved vector logos and brand assets I've created as EPS. But I'm looking to save them now as PDF. I have a few questions:
In Illustrator > I'm going to need to fit the artboard to artwork > save as > Adobe PDF >
Then Adobe PDF Preset > PDF/X-4:2008?
Compression – don't need to consider because the artwork will always be vector
Marks and Bleed – not necassary
Output

This test logo is in CMYK colour mode.
Color conversion - I presume I don't want the PDF to convert or change anything? And for RGB logos I wouldn't want the PDF to convert colors either?
Output Intent Profile Name - that seems to be correct for CMYK FOGRA39 standard
Advanced - nothing to think about or change here.
Security - not necassary
And that's it, or am I missing anything crucial?
