A useful aspect of Lockdown mode (on top of it potentially being quick) is that you can still get into the camera without unlocking it (for me it’s a double tap on the power). When you’re locked down they can’t navigate to your photos, but you might want to be able to record things.
For Android, a reboot forces a pin code.
There’s also ‘lockdown mode’ which forces a pin and hides most info from the lockscreen.
Long-press power, then select ‘lockdown’. (you may have to enable this feature in settings)

And to get the reboot option on Pixels, long press Power and Volume Up. Infinitely more annoying than just long pressing the power button.
What? Do you mean to get the pop up on screen? That’s still a simple long press on the power button. I just did it now on my Pixel.
Long power + Vol Up does a hard reboot directly without calling the power menu
Default after Pixel 5 is to bring up Google Assistant with a long press of the power button.
Then they must have changed their minds again, I haven’t changed this setting so it’s default has been long press for power button
But I did find the setting so you can change it and not worry about it anymore: Settings > System > Gestures > Press and Hold power button
But it also takes like 10-15 seconds of holding it. Not something you can do when a cop holds out his hand for your phone.
For a hard reboot yea. It’s faster to do the onscreen menu which pops up in like a second
Or you can root and restore such powers to Tasker
This is the case on iOS as well but restarting takes longer and more explicit interactions than pressing a button five times
