What lens for a talking head video if I don't want a blurry background?

I'm purchasing an FX30 camera for shooting talking head videos.

I don't know exactly what information is important to share so I'll try to share everything that may be relevant:

* Shooting in my home office * Camera will be 4 feet in front of me * Wall is 4 feet behind me * Would like to show 2-3 feet on each side of me (so 5-6 feet total width) * I know it's trendy to have the background be blurry, but I'd rather people be able to see what's behind me without things being blurry

If you need any other information, let me know.

Thank you!!
