In the US for home connections (cable, fiber, DSL) everybody gets an accessible IP address pretty much -- the worst is that some ports are blocked like port 80 or 25. Phones don't get a dedicated IPv4.

In other parts of the World that didn't get as many IPv4 addresses as the US, the standard for home connections is that you DON'T get a public IP address, you get a private IP address behind carrier grade NAT

And that's really NAT, not a firewall, so nothing is "blocked".

You do get public IPv6 addresses from some ISPs, though.

Finally some truth.

For most people it's dynamic. Mine is dynamic with the PPPoE fibre session.

I have a rpi set up with a minutely cron job to update my domain name to point to home. Works pretty well. At the worst you lose connection for a minute but usually the IP address only changes when the home connection fails which can take more than a minute to reset anyway.

Dynamic in theory, but for many people the IP is unchanged for a long time. I remember reading an article that said the average length of time between dynamic IP changes tracked by some company was something like seven months, though I can't find it now.

I have cable with a theoretically dynamic DNS but it's changed once in >4 years.

You can usually get companies to drop the blocked ports though if you call customer service.
