Valid concerns, you need to pick your VPN carefully if using a public provider. In my case, I relay everything to a VM I trust that is running a firewall and AdGuard for DNS ad-blocking.
The system may not work for everyone (for example, streaming services optimize based on your location, which will break down if the VM lives in some cloud), but I use my phone for music, browsing and email (not video consumption) so it works for me.
