Unless you’re using 5g NR SA which is the actual 5g - New Radio Stand Alone, which is supposed to be able to function, as the name implies, alone, without any fallback to insecure networks.
If you’re using 5g NR NSA it still requires 4g to function.
I am in airplane mode 99.9% of the time, using wifi calling (sms/rcs also work over wifi), so my phone isn’t susceptible to imsi catchers and such or location pinging.
The WiFi calling can be a bit buggy. Sometimes I answer the phone and there’s no audio. I have to reboot the phone to get it to work again. I should just get a VoIP line to use at home.
If you’re that paranoid, then you shouldn’t be using RCS. It’s owned by google. XMPP and Matrix are secure, decentralized alternatives that don’t give your data to google.
You’re more secure using wifi calling anyway.

Yes, I’m paranoid.
Everyone should be.
