It may be on the older side, but I've been using my Pixel 4A for three years or so, no complaints. I also use the headphone whenever possible. Also using GrapheneOS.
You may want to check out the Pixel 5A (also has a headphone jack if I'm not mistaken) for a bit of a newer phone, but the one I got used seems to have a band issue in which it would forcefully shut down after some time with my SIM card.
Aside from Nvidia drivers, Void is home.
