Pixel 4a here. Great phone, just in desperate need of a battery replacement. Checking ifixit the risk of breaking the display while opening the phone seems quite high :/
Yes, I spent years breaking the screen of this phone and eventually replacing it. I've finally got a screen protector and it's been great... But the screen will almost certainly crack when you remove it. Bummer about the extra cost.
Samsung Galaxy Xcover 6pro has been pretty good for me. It has a headphone jack, SD card slot, and a removable battery. The specs aren't the top of the line, but as long as I'm not playing games on my phone it gets the job done.
The Samsung Galaxy A15 5G has an audio jack and is somewhat recent. It's a budget phone, though. The spec's aren't the best, but the price point is nice. If you wanted to listen to flac over wired headphones, that would work well.
