..There is one fairly good article about changing these names in Apple Support..
• Change the name of your macOS user account and home folder - Apple Support
https://support.apple.com/en-us/HT201548
"You can rename your macOS user account and home folder, which were named when the account was created."
The name of your macOS user account and the name of your home 🏠 folder must both be the same.
Details in article are specific, with both re-naming regimens
being separately stated; so they later still work together.
"Because doing this incorrectly could damage your account and prevent you
from logging in, you should back up your important data before proceeding."
Good luck & happy trails!🌤🌻🌿❄️
