I use primarily debs but if your using Ubuntu it will include Ubuntu supported snaps. This is all from the distro supplied repos generally.
Installing random stuff not distro support contains a lot of addition risks such as potentially more bugs and malware.
I think the only 3rd party program I have installed is an AppImage of Joplin. I found the snap buggy.
I am not big fan of snaps or flatpacks as I had issues with both. One rarely needs them on Debian based distros anyway.
Look at FairPhone. I got a Pixel 8a recently and flashed Graphene and I think this is the best tradeoff but I understand wanting jack etc, as I would have liked too.
In hind site for me, turns out Blutooth is great as it works well with my OTC hearing aids and my Bluetooth headphones too. I liked the hearing aide support as it gives me proper calibrated sound where generic stuff will not.
