Bluetooth everything that requires location permissions.
Why u need my precise location to turn on a lightbulb?

I’m not sure how many people know this but there is good reason why (at least on android) giving Bluetooth permissions also requires location permissions.
The basic concept is that given enough Bluetooth data an app can pinpoint your location accurately anyways. So the android devs decided that they would just require any app that wanted Bluetooth data would also need to require access to location. That way users would be indirectly informed of the dangers.
Why not just a pop-up to inform of the danger? Probably because most users will click past that warning and not read it.

That’s just classic android retardation at play.
Literally just making the bad guys’ jobs easier.

that really depends on the location. not everyone lives in big cities. is there a way today to give access to bluetooth without giving access to GPS?

Every Bluetooth device has a unique identifier. Any phone that has seen that Bluetooth device in the past could have told google/apple/whoever “hey BTW this device is at those coordinates”.
Google already uses this with WiFi to help “bootstrap” GPS localization. It is much faster to get a GPS fix if you already know roughly where you are (a few seconds vs a couple minutes), so they use nearby WiFi/Bluetooth devices to determine that. Remember 10-15 years ago when getting a GPS fix took forever? GPS didn’t change, this did.
Apple went further and does this with Airtags now. Every Bluetooth device that ever went near an iPhone is in Apple’s database with GPS coordinates.
So unless you live alone in a mountain cabin that has never been visited by someone with a smartphone before and you didn’t disable the “enhanced localization” feature on your phone, yes your Bluetooth is at risk of giving up your location.

bluetooth is short range isn’t it? so while this is a problem, it is not the exact same thing. network based location is not a replacement for GPS.
I think you mean A-GPS, which is not related to wifi and bluetooth, other thqn being able to use wifi to access a server for downloading current constellation data. phones that have google mobile services installed, have an additional fused location source (besides a network based and a gps based location source) that tries to fuse the 2 sources while the gps signal is not precise enough
