Calling a 3:2 display a con is a bit harsh considering it's very much a personal preference.
If you're primarily a media consumer then sure, 16:9 is preferable as you end up less letterboxed with most contemporary media. This being the case, you might have been better off waiting for a Framework Laptop 16 with its 16:10 ratio display. I believe it also has better speakers.
If you code, edit documents, basically anything that involves vertical scrolling through stuff, the more vertical you can get the better. It also affords a deeper palm rest without having a stupidly wide chassis.
I have a super-ultrawide on my desk, but although it allows for two native 16:9 windows side-by-side, it's more commonly arranged with thee square-ish windows across its width as unless I'm doing something very wrong with Python, I really don't need the width. More vertical, more better for my use cases!
FW13 AMD and Debian Bookworm gives 3-5 hours, but I'm almost exclusively tooling around with GNUradio and so on, so don't for a moment consider that to be a realistic figure for "normal" use.
