IcyScroll I'm curious to see how the official stance on LTE and 5G will be updated
I would not expect anything to be changed. The purpose of these features remains attack surface reduction, by allowing the user to enable only the minimum set of protocols they require. The latest changes merely provide more flexibility than previously.
If 5G offered any significant security improvements (or known additional risks), that would likely have been discussed extensively here, and a 5G-only feature would have been added much sooner.
Bottom line: the previous advice should still stand. Avoid cellular networks if you can. If you must use them, enable only the protocols you need to get coverage in your area.
