Originally, the database limitation was/is 4000 files for the internal memory and 4000 for the external. Note, however, that long file names and deeply nested folders will take up more than one database entry.
Also, this is the current state; the database capacity likely will go down, and perhaps significantly, with a firmware revision--hopefully to be known yet this month.

I'm not sure if a 64 or even 128 GB card would work anyway. My attempt with a SanDisk Mobile Ultra 64 GB (formatted to Fat32) in a Clip Zip wasn't successful. The player only took notice of half of the card content at best and was extremely slow.

Again, that may be the result of the original firmware's database limitations. The alternate Rockbox firmware does not have those limitations.
Others have reported using a 128GB microSD card in the Clip without issue.

Yes--again, due to the original firmware's database limitations as to the number of entries it allows, Rockbox would be necessary to use the extra space in the mega-sized cards (unless one's files are large in size, thereby limiting the number of files that one has and thereby the number of database entries).
One thing I'm unsure of: if one only uses folder navigation on a Clip+ or Clip Zip, could one fully use a mega-sized card with the original firmware? If I recall correctly, the answer may be no there as well.

I don't think so. IIUC, the 'folder' view in the sandisk actually uses the same database, but instead shows the file paths.
Large SD cards might still be useful though if one has a lot of very large files (e.g. FLAC, audio books, etc).
