Wich one for my mid-2011 iMac 24''?

Hi, I have a mid-2011 iMac with 24GB of RAM and an SSD (which I combined with the native HDD to create a Fusion drive).

As far as I know Ventura seems to be the most stable OS. Is It true?

I read in the OCLP info that, in addition to not having a Metal graphics card (I have an AMD Radeon 6750M, but I don't play games or do any graphics/video processing), there's a problem with the USB 1.1 ports, which I don't quite understand.

I currently have a wired Apple USB keyboard and a Magic Mouse 2 connected via Bluetooth. I'm connected via Wi-Fi.

Could I have problems with the keyboard and mouse or Wi-Fi?

In the end: wich versione can be the best choice?
