Audio guy buys video equipment for the first time, can you help me avoid mistakes?

I'm aware, what should I buy posts are not the most sought after but last time I ran my purchase list here I got so many people helping me to make a better decision. For example I've been suggested against the CFExpress card and that suggestion turned out to be absolutely true, I could've bought 2 v90 cards and have much more capacity. Oh well!

So this time I'm asking a little earlier before putting the order in. I'm shooting mostly interviews for a non-profit, pretty much helping them and their cause.

Here is what I'm planning to add to our interview setup in addition to our current Sony FX30

Sigma 18-55mm

DJI RS Mini 3

To be ordered

LENS

Sigma 30mm f/1.4 DC DN Contemporary Lens (Sony E) $289

-Buying this to get a little more background separation but not sure if I should go for 30mm or 56mm for interviews. Current zoom Sigma gives most separation at the longest focal length so I thought going for 56mm but with the crop of the camera, I'm not sure if it's gonna be too close in closed spaces https://www.bhphotovideo.com/c/product/1234027-REG/sigma_302965_30mm_f_1_4_dc_dn.html

Long post but I'd appreciate any suggestions and comments. I'm open to suggestions of other equipment if I'm missing anything as well!

I'm aware of the limitations of bi-color lights and variable ND filters, but since most of the time convenience is important due to run and gun situations I've decided to go with these options. Thanks!
