Why not just stay on the previous 15 release? They still even push updates for it!
On my M2, I have kept it on 15 but Apple aggressively tries to trick me into upgrading in a way that reminds me of Microsoft's behavior with Windows 8/10.
I just buy older stock or refurbished these days. M1s and M2s are still good enough for me. Recently picked up a refurbished M1 16" because I wanted a larger screen in bed / on the couch for a good price with good condition refurbished from amazon.
