Yes, indeed, if the major hardware features work it is save to move to sailfish. There are many quirks in the official android still.
You might want to try to get a GPS fix in Android to confirm it works since that is one of the few unsolved issues. For most sfos Pro¹ GPS works in sfos, for few not.

Even if you discover problems much later it is possible to fully backup sailfish to sdcard, flash android to test hardware, then revert to backup as proven by @kabouik

Congratulations on getting the Pro¹ delivered!
Such a relief to see things move again.
