Acrobat Express -- How to Use on the Desktop?

I’m new to Acrobat Express but fairly familiar with the old desktop Acrobat Standard.  I know Adobe is not keen on User Guides or Reference Manuals, but I need something like that to learn how to use this new tool for desktop PDF handling.

I can already see that essential PDF tools, such as editing, organizing, etc., are missing from this version.  I have no interest in the AI assistant, nor in any of the flashy graphic production that it seems to feature.  This seems to leave me with only the ability to open some image files (e.g., scanned output) and export them as PDFs (from which MS Word can take over to make them editable); or with a substitute for Acrobat Reader to open PDFs.  This doesn’t seem worth paying $110/year unless I’m missing something!?

I don’t want to spend $240/year for Acrobat Pro, though that seems to be what’s required to do what I used to be able to do with the old Acrobat Standard 2017!  Is there and upgrade path (without loosing the money I’ve already dropped on the year subscription) to Acrobat “Standard?”
