I would be careful with LaTeX. I use to have a LaTeX resume generated with LuaTeX. At an old company, I saw my LaTeX resume in the ATS long after I was hired. Apparently, something happened and the PDF displayed as blurred-but-not-unreadable in the ATS. Maybe the ATS did some post-processing or used a limited PDF display engine? Lucky for me, the resume for that job was just a formality. These days, I just use Google Docs and export to PDF.
I don’t know of the example systems but I’ve applied to a handful of companies recently, all running the same-ish workday resume ingestion. You can actually tell which are running a more recent version because the parsing is more accurate.
There is also a common no-account single page application software, I checked at a company I’d applied to and it was called Lever(?)
Normally, I thought for ATS parsing if you upload in an application and a few of the prior experience text boxes are accurate, then you’re good. I’ve always had to fix my experiences though, even with using a word doc.
