As a macOS sysadmin I feel this in my bones, and of course I don't know what apps are essential for you, but FWIW Sequoia has been basically identical to Sonoma for me. In fact I had to double check what I was running on this computer before writing this because there's just no functional or aesthetic difference that I know of off the top of my head.
(And yes, I'm holding off on Sonoma for as long as possible because... yuck)
