Apologies, I did not read you post carefully enough

SM7B and cloud lifter sounds with the Zed10i seems like a proposition now you have the budget as that will get over the lack of sensitivity issue any dynamic mic will have for your usage.
Anything you can do to reduce background noise (computer, traffic noise, wife and kids, but good luck with that last one

) will be worthwhile but bear in mind 'soundproofing' is difficult and expensive so you just have to do the best you can.
Study the polar patterns and get the computer in the mics null, work close (you may need a pop shield) and get plenty of acoustic treatment, I believe radio studios are usually pretty dry acoustics and much quieter than it is possible to get in a domestic environment.
