couple of Qs, due to problems with my MacBook Pro with fans, battery, etc.

I have a couple of Qs, due to problems with my MacBook Pro with fans, battery, etc.

I have a backup, and I will get it to the service center, and wanted to reset it === Leave ONLY MacOS + App, all other data delete...

If I am having [currently have ONLY One Admin account] two Administrator User Accounts on my MacBook Pro, their user files, should be different and separate, or will have common/the same files?

Exist any method like in Windows 10, to RESET my MacBook Pro Monterey, so all Data gone and unrecoverable, also all Apps' personal files deleted, but the OS Operating System, macOS, and system files & Apps remain…?

Also, is any way along with MacOS, to keep my installed Apps but, WITHOUT my Apps' personal data…?

It is a FANs problem I think --- IN CASE of FANS are PROBLEMATIC - What is the symptom...?

Symptoms in my case
###################
A message appeared for the battery - I do NOT plan to change the battery
Fan problems - needed to be checked
Sometimes fans stop and a sound listen, after fans start, repeatedly this
Sometimes fans stop completely and the MacBook restarts
Copying files from The MacBook to USB Stick (3.0 ex-FAT) is extremely slow

Honestly it just sounds like your fan is about to fail. It was cheap and easy on my 2014, but here are the instructions.

MacBook Pro 15" Touch Bar Late 2016 Fan Replacement

Use this guide to replace a broken or noisy left and right fan in your MacBook Pro 15" Touch Bar Late 2016

As far as user accounts, one way to do it is.
1. Backup your computer
2. Create a new admin user account with simple password
3. Delete your other user accounts.
4. Launch your apps to make sure that your account info isn't still in them.

Just restore your user accounts when you get the computer back from the service center.
