Just in case you weren’t aware, the Edge Insider Preview has an Enterprise option that allows you to sign in with your Office 365 credentials.
and is also available for MacOS.
I will also say that having now used Edge Insider Preview for a while, I can thoroughly recommend it and have never had any troubles. I really like all this integration when you look at Windows 10, Azure AD, Microsoft 365, Office and now Edge.
