For me personally that’s too boring.. Long range is illegal in lots of places; in the US you technically need a spotter and the craft needs to be in direct line of sight, and pretty close because it should be visible with unaided eye - so, no binoculars.
3.5" is the sweet spot where you can build a sub 250g (or almost sub 250 - do cops really carry kitchen scales on them?) drone with decent performance that doesn't scare people when you fly around and still has the performance close to a 5" one and you can still do all of the tricks. The only drawback with 3.5" is that they're more susceptible to wind, so if it's always very windy where you fly, maybe consider a 5". Oh, and you also don't need to install a remote ID module on a sub 250g quad.
