I’ve created a new user/account and uploaded/synced my music collection with that account.
I’m now trying to set up read only share for that account and while I can do this for each subfolder (there are over 500 of these) I cannot do this for the top level

I think it is not possible and not wanted. It also makes (mostly) no sense.
Normally users do not want to share all directorys and files.
But you can move all folders in one new folder and share the new folder.

folder music
subfolder ABBA
subfolder AC_DC

Look also Group folders.
Does not solve your problem but maybe nice feature in a similar direction.

Yep, thought of creating another folder and then moving everything into that subfolder, but not sure what the impact of the move is on the clients that are currently synced to the top folder given that the collection is close to 400GB.

Yes. i had asked myself the same question but had not written it in my post.
But i think you must change it.

I think the question is more as to what Nextcloud does for a file move.

Does it just update some file pointers (little overheads) or actually copy the files to the next location (massive overhead).

I think it just moves pointers. I just conducted a simple experiment where I added a 2mb file to the root directory on a synced desktop (1), and then moved this file into a subdirectory (2). Here is my network traffic (red is up, blue is down):


As you can see, the second peak is much smaller.

The sync client records the move event as “renaming” the file:


You might construct an experiment along similar lines using a larger file, and perhaps try doing the manipulation in the web client instead of on a desktop client—only the latter was tested here.
