Silent I guess if all carriers are shutting down 3G voice then the privacy implications don't really matter. Then my choices becomes VoLTE or the new VoNR on 5G.
I think that's accurate.
Silent I know 5G is probably worse for privacy due to the extreme geolocation precision
I have heard that meme a lot, but personally I'm not aware of a strong analysis. For example, I don't think mmWave 5G is all that prevalent.
I think 5G enthusiasts (e.g., people who wanted government subsidies for rollout, people who wanted everybody to hurry up and buy a 5G-capable handset) went through a period of claiming that 5G would be so! much! better! in every way, including that if you lost your phone your carrier could tell you which corner of which shelf in your garage you had left it on (woohoo!). And it's true that mmWave cell sites would need to be more dense if they were widely deployed, which would tend to improve localization precision.
But personally I haven't seen anything indicating that 5G in practice means your carrier can tell which bathroom stall you're in. And meanwhile, personally, I have set my phone to prefer LTE because I think it improves battery life and network stability.
