Can or should I use my work account to log into a laptop I get from my workplace, or is the intent that workers log into their work-computers with personal microsoft accounts?

Question

We are a small business, with office 365 work accounts.

I am not an IT professional, (I am a constructional engineer) but I am attempting to sort out our microsoft products and services for our office as I familiarise myself with our tools as a new hire.

So currently we have various different ways of using our services for this at the workplace, however I have taken it upon myself to streamline our workspace, help people get used to currently unused functions and make better use of the services we pay for. Some swear by only using online versions of office programs, some use mainly the downloaded apps on their computers, some have personal microsoft accounts logged in and some simply have no such account involved.

Furthermore we are currently brainstorming ways to consolidate the services we use, like possibly switching from Dropbox to Onedrive, a service we already pay for that so far has seen little use. I am also looking into making use of sharepoint and other services, but I need more time to go through this.. it is only day 4 after all.

As part of this effort, I am trying to get full access to all windows services on my computer, but it seems to want me to use a microsoft account and gives me the "vibe" that I haven't "unlocked" the full potential of windows when logged on with my work "microsoft 365 account" and not a microsoft account. (For example I am unable to set up fingerprint login currently with no "microsoft account" on my laptop only a "local administrator")

So how is "work-account" vs "microsoft-account" intended to be used and what do you recommend doing in terms of login procedure on our office/work-laptops?

You have my grattitude for your patience and time.

Kind regards

An enthusiastic, and newly hired engineer.
