Wifi+5G can be together always enabled, without security issue?

If I am home, I am only using Wifi with 5G OFF. If I am out somewhere, work, etc. I use 5G with Wifi OFF. **The question: can I enable Wifi+5G always ON?** Thinking of security issues like: - if someone can break in to my phone via the internet/5G network, it can see my internal network (since Wifi is ON) - if Wifi is always enabled while I am outside home, can it be used maliciously? eg.: forcing my phone to connect to a fake wifi network?
