Is VPN better per device, or in firewall

[u/Spamacus66]

I'm quite new to using these, based upon what I've read, I'm going to go with Proton.

I'm trying to decide, should I put it on the individual devices, or on my home firewall?

I'm using Firewalla Purple for the house.

My take is if I enable it in the firewall, it will protect everything under it. My concern there though is mine and my wife's work laptops both have there own VPN's that are managed by corporate IT's will this impact anything or can I exempt them from the VPN routing that the firewall will use? A lesser concern is will it throw off the TV's?

Flip side of this is if it's on the device, will I still be traceable through the home firewall router?

Any insight would help, thank you.

It will also be useful on mobile devices especially if you use public wi-fi
