Sometimes I connect directly to the ISP at one of my homes, and at other times use (Proton) VPN. Is one way more or less likely to use a NAT? Is there a way to tell if I'm behind a NAT?
Both ISPs and VPNs rely on NAT for home customers, in the case of VPNs, some providers offer a unique IP at an additional cost. NordVPN charges an extra €4 for a dedicated IP. ProtonVPN only offers dedicated IPs on its business plans.
The most practical way to know if you have a unique IP is going through the router's settings, under the WAN page:

In my case you can see that I am assigned an IP starting with "100.68".
Anything from "100.64" to "100.127" is reserved for NAT use.
