Why do you feel it is harder in Windows? In Windows 11, go into the Settings app, search for 'Path', then choose "Edit environment variables <in system/in account>". You then get a graphical method to add/edit/delete entries, and the paths apply to any application you run. No need to find a dotfile to edit. No need to know how to format a particular entry, or chain it with the existing $PATH.
On macOS it is arguably harder as you need to use Cmd-Shift-. to reveal dotfiles should you be uncomfortable editing them with vim/nano/etc. When using Omz with Terminal, a path entry could be in any number of files supporting Omz along with my zshrc. Windows doesn't have this issue.
Windows has it's issues, but env vars are significantly easier to manipulate without much knowledge.
