When my Pixel 7a decided to become a bomb (battery leakage), I was doing some research on good phones and looked into a few of those. As far as I'm aware, there is no Linux phone that is currently developed enough for daily use, for various reasons including battery life only lasting an hour or two.
I ended up going with a Fairphone, which I think was a great choice and will hopefully last me many years. At the same time, it ultimately relies on Android, which is why at least for now it's not a real alternative on the software/OS side..
I guess the main problem is when universities, employers, etc. require that you install an app for access to some essential part of your business with them. That's the kind of application that cannot easily be replaced with an open source equivalent, and will unfortunately probably tie many to proprietary versions of Android in the near future.
Some of the time using these apps can be avoided, but I'd imagine this is only temporary, and either way it adds significant inconvenience a lot of the time to try to go without them.
