Perhaps there may have been an increased margin of security from the forced access
some have tried; should the device have seen the most recent iOS update/upgrade
prior to confiscation or attempts to access contents by outsiders using modern tools.
While there is a good margin of security, hard to say to what depths some government
agency may go; also some regions could use harsher techniques of experimental type,
to attempt to force-access the iPhone build model & its iOS level in use, such as yours.
As not all iPhones could benefit from most recent security upgrade near iOS 16.5.x..
...The best you might do, may be to see how the unit might be accessed by you, with
iCloud.com & erased before any agency might get your personal private information.
That's where you'd use a Mac or PC + web browser, to login w/ your Apple credentials.
If not done correctly, this could remove any security the lost iPhone might already have.
(And your iPhone might then be totally lost to you, if this were done.)
That said, I'm not an expert by most definition. ~ Best of luck to you in any circumstance.
