Samba (Windows access) and Firewall on Fedora 31

Hi, folks!
It's been a while since I've been on this forum.

I have a fresh install of Fedora 31. I'm trying to set up Samba for Windows machines' access. I used to the GUI versions of Samba, Firewall, or Users. I find that there are neither of these are available for Fedora 31.

Does this mean I need to use the CLI method for setting up Samba and Firewall? Or are there some alternatives?

I'm wanting to share several folders on the Fedora to be accessed by Windows machines. I'm able to ping in both directions (Fedora and Windows 10). I can read and write to/from an older Fedora 22 machine, so I know the Windows 10 isn't the cause of grief.

I'm getting a lot of exit-code errors and have no clue how to decipher those, even in my logs.

Any help would be appreciated. Thanks much!
