Decrypting the 4g/5g network will require a key from the telecommunications company. I argue it’s insignificantly less secure because a malicious actor can intercept it and decrypt it if they manage to steal the key from the company.
Practically, only your government would be able to get a copy of the key. But they’d also be able to watch your actual cable internet as well. And when your government gets interested in you then you fucked all the way up.
Using a VPN makes the original question redundant. The VPN would have everything super encrypted for either home wifi or home 4g/5g. Your question transforms into “can i trust this vpn company”
Say you access a VPN located over seas from your phone while on mobile data. Then your traffic is encrypted and your mobile data provider (for your phone) should only see traffic to one IP address.
Say you access the same VPN while at home connect to wifi or Ethernet on a PC (or on your phone), then your ISP should only see traffic to the one IP address (that’s located over seas).
Now let’s say your are tech savvy enough to run a Wireguard setup and or Tailscale setup at home and make your own VPN. Then you access that from work or from overseas with a mobile phone or laptop. All your traffic should now show as connecting to your homes IP address directly, but keep in mind your home ISP provider then sees you connecting to sites like Google, Facebook, or Lemmy.

But wouldn’t a VPN be encrypting my cable internet traffic? (Same for VPN on the phone)

That depends where your VPN is.
Say you access a VPN located over seas from your phone while on mobile data. Then your traffic is encrypted and your mobile data provider (for your phone) should only see traffic to one IP address.

But what if I VPN into my home network and redirect that traffic through a provider’s VPN…
