I only park it in fairly secure locations if it's for more than a few hours (ie. not in the street), and I put 2 of the most secure bike locks I could find, 1 wheel lock, secure bolts on wheels and saddle, and light locks on big accessories like the child seat. Plus an Airtag hidden somewhere.
The trick is to have a bike which stands out. If you can recognize your individual bike from across the street, people won't steal it. Bonus points if it looks crappy despite being well-maintained. Beyond that it is mainly a matter of parking in bike garages with cameras where possible, and using a chain lock to fix it to an immovable object otherwise.
The sad thing here is that it's not even triaging by property damage. Your €1000 fifth hand car will get more police attention if stolen than a €3000 ebike.

Bike theft is so rampant. It's just so easy, throw it in a truck, or pedal away with it. Since I live in a redneck place, I ride a step-through woman bike in pastel color now, after two previous ones got stolen, and that genuinely helps. People may make snarky comments, but the bike has remained untouched for a decade now.
