As you found, the ability to check your Music Library storage limits is restricted so you have to submit a diagnostic and request (with the number) that Sonos staff take a look at it.
There are tweaks you can try to reduce the storage needed if you are near the limit.
@Stanley_4 is correct about the tweaks - I didn’t mention one of them as I’d already rejected it myself.
Sonos only uses the tags, so you can reduce the store by changing all the filenames and, preferably, path names to something much shorter. This may reduce the amount of store to under the limit, but won’t help if you actually have more than 65k tracks.
As I mainly use the folder view this is no use to me, but some may find it an acceptable compromise.
I’m not changing my data as eventually I’ll move to a more capable system that can handle the full data. Indeed, the casting approach already does that, so my backup plan is already in place ;-)
I keep a master copy of my music and a copy edited to deal with the many things that seem to upset Sonos. If I ever switch I can just delete the Sonos copy.
I do the same for my car that can’t deal with FLAC so I have another edited copy for it in MP3.
Not great but it works while complaining about the issue hasn’t so far.

I’d imagine that we’ve all found our own ways of coping with the deficiencies of the Sonos system that suit our particular needs… I have no intention of maintaining two separate 800Gb datasets (which require backing up) just because Sonos functionality is sub-optimal.
If I become worried about it I can always switch to the casting system, which has none of the Sonos limits and doesn’t need me to keep a separate data set.
