No WiFi 7 and WiFi 6E only is annoying. Especially for what they are charging. And Bluetooth 5.3, Their Pro Mac are slower than their iPhone Pro.
SSD has double the speed. I guess they say this only for M5 MacBook Pro, because the previous M4 has always had slower SSD speed than M4 Pro at 3.5GB/s. So now the M5 should be at 7GB/s.
The non-pro/max chipped MBPs have always been a little 'lower spec' in several regards. There used to be a little more separation though, with the non-pro chips available only in the Air & 13" MBP, but back then people complained about Apple having 'too many models'...
I suspect the M5 Pro/Max chipped MBPs will bring some of these improvements you're looking for.
Just things like waiting on the download for an Xcode update before I can get to work would be a lot more tolerable on 1.4 Gbps than the like 600 Mbps on the WiFi 5. Or worrying if this video is buffering because a backup started in the background.
But I gave up on waiting and just got Ethernet put in in the places where I'm likely to sit with my laptop - now I plug in to charge and automatically get 2.5 Gbps Ethernet at the same time using a USB-C dock and a long USB 3 cable.
With NVMe NASes and 5Gbit, 8Gbit and 8Gbit FTTH available for reasonable price in many places, it's easy to saturate any WiFi connection by just downloading stuff (games, AI models, etc), backing up files, or accessing your files on NAS (and editing videos straight off NAS is recently trendy).

I assume no update on SDXC UHS-III.
