(UK here, things will vary from place to place) Long-established ISPs generally have real IPv4 addresses to give out, though they are not statically allocated. If your router is on 24/7 you tend to have the same address for a long time, but it isn't really static. Newer ISPs are more likely to be using CGNAT. True static IPv4 is available from some ISPs, particularly those that target small/medium businesses as much as (or instead of) residential users. On mobile you are pretty much guaranteed to be behind CGNAT, though I don't think anyone would expect to have anything remotely static in that circumstance anyway. I have static IPv4 at home (actually a /29 – I've had this account long enough that it wasn't difficult to get back then, and the ISP is more commercially targetted), and VPN to that when mobile. Probably makes me easier to track by stalkers not blocked by PiHole and other such provisions, but it does mean I don't often see CAPCHAs. My VPN use is for protecting myself from potentially bad local networks, rather than hiding my ID or falsifying my location (or where location matters, I'm pretending to be at home not some other place), which is a different set of priorities to many.
