I've tested sorting data in Google sheets with a small number of records (10) and the sync still worked fine.
Even adding a record then sorting and syncing still kept the data intact.
This was only a small number of records, there were only three data fields in each record, and the data was sorted using the data sort functions in Sheets.
I didn't try manual (cut & paste) sorting.
Formatting the data should be fine. It only changes the presentation, not the underlying data.
However I haven't tested it.
Why not try both procedures on a copy of your own data, to see if they work for you.
As always - backup your data, and copy it to an external device before experimenting.
