Very important questions BEFORE I install full version of Windows 11 Enterprise

The ONLY way I will consider going to Windows 11 is the Enterprise Edition (64-bit ISO).  I have some questions. I use Steam for games. Furthermore, I use Office 365. Will both those programs, games, my nVidia RTX graphics card work as normal, just like in Windows 10 Pro and 11 Pro??? And eventually I may want to use a local account only. But I know if I install and use Office 365 I will have to sign in to download and install or check my account profile, payments, etc.
