Data migration from 2015 BigSur MBP to 2021 M1 MBP

I want to migrate all data from my existing 2015 MBP that runs on Big Sur to the latest 2021 MBP with M1 Pro chip. I want to be able to transfer all files and all settings to the new MBP and this includes the hidden .ssh folders, /etc/hosts files, to name a few. I have read about Migration Assistant being able to do this over Wifi but quite unsure if all the data & apps will get transferred or not OR if it cause issues because the OS versions will be different. Can I use CarbonCopyCloner and "clone" my old OS + data on the new M1 MBP which runs on a new version of MacOS? Which OS would be present after cloning? Would the new OS cause issues especially since I am on an Intel MBP. I will have only a weekend to complete this process before I have to ship my old MBP so looking for best practices from people who have completed this process before. Basically want an exact copy of what I currently have in my 2015 MBP to avoid any troubles with office work.
