Lost phone & all notes (my book). Are they in Google Backup?

Wrote my life's memories on NOTES for the 2nd time. Last time, I switched from (lost) Huawei to Xiaomi and thought they were not restored because of that. This time, I restored my Redmi 10C data, stored on Google (not MiCloud) to Poco X5 Pro AND AGAIN LOST ALL NOTES including my notes for my book and financial data. Does somebody know if I can FIND MY NOTES somewhere? My backup is 10 days old. I just restored it an hour ago (April 18, 2024). I read that deleted notes can be restored for a couple of days. Could maybe help if I wipe my phone via the Find My Device function when the thief charges it? Would they then be stored in the Google Cloud/MiCloud and could then be restored?
