Which MacOS is more convenient in my case?

Hello! I have a MacBook Pro 13” Mid 2012 (MacBook 9.2)

It has 16Gb of RAM and a 2.5GHz Core i5 Processor.

I have installed a 500gb SSD

and it already has OpenCore, currently with MacOS Sequoia, however I feel that the computer is too slow and all the time without carrying out any process the fan is running, is this operating system convenient or should I put a less demanding MacOS, what do you think? Thank you very much for reading this post.

Greetings!
