No. By definition, last mile ISP sees 100% of net-bound traffic. "Various CDNs" itself already represents a dilution of that view, and are not universal themselves. It's an inherent improvement even outside of other factors. But there are other factors, including a decrease in the level of natural monopoly. Last-mile ISPs often have zero effective competition, and even with one or two there are often high change over costs, longer term contracts involved, etc. The closer you get to the net's core however, the more bandwidth there is and the more players there are and in turn vastly more competition potential. That's not a guarantee sure, but it absolutely makes a difference. There's also a limiting factor principle at work: even if you do trust a given ISP, how does that help you avoid CDNs anyway?
It's the same reason that spinning up your own instance of an algo VPN on some VPS and funneling all your home and mobile traffic through that may have practical benefits. Sure in principle the VPS (or data center if you go on your own metal) provider could try spying as well. But competition there is fierce, the average technical level of users is higher, major business interests are involved in reputation, and swapping to another provider is utterly trivial. The incentives and business models for the likes of Amazon/DigitalOcean/Google/Microsoft/OVH/Scaleway/Vultr/[...] in their compute offerings are completely different from the likes of AT&T/Charter/Comcast/T-mobile/Verizon. So it is in fact reasonable to expect a difference in the level of shenanigans too, and hey, if not you can easily move, which also in turn makes it much easier as a practical matter to retaliate (sue), which virtuously further decreases the likelihood of shenanigans.
You have a contractual relation with your ISP and they're in your jurisdiction so at least in theory you have legal recourse.
Advocating for ESNI on the other hand means argueing for more centralization towards entities which are far more removed from you where you have little recourse. So as far as incentives go they may be more beholden to some law enforcement agency than you the non-customer.
There are difference, but it does not appear to be an obvious improvement to me.
I think you bring up good points but your takeaway is 180 off.
Different jurisdiction means less likely to be answerable to your local government should they be oppressive.
The fact you don't have a contractual relationship with a CDN is a good thing because it becomes trivial simply to stop using them, should the need arise. Don't like Cloudflare? block them. Your choice of websites will be reduced greatly but you still have an operational internet connection.
