Best affordable RE20 Interface (first XLR mic)

[Mr Technician]

I am purchasing my first "proper" mic for the purposes of recording videos, streaming, and Zoom calls.

 

Having done some research I am attempting to avoid the SM7B hype (even though it does sound very good) and have been impressed by reviews of the RE20. I am debating which interface would be best suited for my budget and needs. My current top contender is the MOTU M2 or possibly the GoXLR, but the latter's features are probably overkill for my present needs (not worth $200 more, anyway).

 

This leads me to my specific questions:

• Should I get a better interface than the MOTU M2, or is anything more expensive going to be unnecessary?
• I am hoping to minimize the voice of someone talking next to me as I share a home office and sometimes have concurrent Zoom calls. Are there any better options than the RE20 for this purpose? (I can also rely on Zoom's processing as any loss of sound quality isn't a concern for meetings. During streaming/recording my room will be quieter but off-axis rejection is still a plus).
