This just totally depends on your country and ISP.
In Germany most ISPs don't even give you a dynamic IPv4, it's cgnat so you share with a lot of other people.
But there are ways around it. I use Cloudflare Tunnel and that way I don't expose anything (I could only do it with ipv6 but in the end Cloudflare Tunnels are easier)
I've got a static IP (v4) too. Used to be Sonic would offer your four IPs for free. Now it's down to one, and only if you're in an area not served by their fiber service. They've backed away almost immediately from the idea of offering static IPs to their fiber customers and I'm pretty sure they don't do IPv6 with fiber either. And Sonic supposed to one of the better web providers out there.
I've also got 10G fiber with them, and at least this time the IP didn't change after they updated the firmware on their garbage ONT. XG(S?)-PON stuff is still real immature.
