You used to have to create a bootable USB, now you can boot into recovery mode, reformat the drive and install any of 3 versions of macOS. The version that come with your machine, the last version of macOS compatible or latest version.
At work we wound up just making bootable USB's, as they Just Work(tm).
How about getting VMs set up with port forwarding?
Also what a time to switch to Mac, the constant Apple news didn't scare you? Do you watch a lot of TV?
Which constant Apple news? You'll find if you look back through my post history I was very critical of Big Sur and the M1 but after taking time to understand it, measure it and use it I'm less concerned. When I put all the vendors on the table, including Linux, the tradeoffs were still in my favour with Apple.
