iPhone backup from iTunes will not restore backup on new iPhone because "there is not enough space on iPhone"

"iPhone backup from iTunes will not restore backup on new iPhone because 'there is not enough space on iPhone': [...]Considering this is a brand new phone, how would I go about restoring this backup I made last night to the new phone? It seems like the iOS data and the System data are taking up space.[...]"

Troubleshooting iPhone Storage:

Internal storage cannot be upgraded. It is what it is. So, the maximum internal storage capacity never increases, even if you upgraded your iCloud plan. Learn More here: What's the Difference Between Device Storage and iCloud Storage? Apple Support

Was afraid that might be the only option but you might be right. Might just pick up a higher storage phone soon and be done w it so I can restore my phone finally.

I'm considering using an app to try and do selective backup so I can retrieve some of my music files I have saved on the backup (I produce music which is why it was so vital for me at first). But for now I guess the rest of the old phone data will have to sit on this PC until the storage upgrade.

Thanks

An app which purports to do selective backup, should be avoided at all costs. There really is no app which can do that and then getting that data back to an iPhone without iTunes or Finder is a recipe for disaster. I'd remove that thought completely. Backups are all or nothing.

Maybe should not have left the store until they had set it up for you, too late now though.

The only ways I know out of it is to borrow a 256GB phone to restore the data to, clean it up, then back it up again.

Or reject this phone and buy a 256GB one.
