It’s too late, right? You already have the microphones picked out?
Again, in my opinion, you would be way better off putting first level soundproofing in so it doesn’t sound like you’re recording in a kitchen or bathroom (even if you are actually recording in a kitchen or bathroom).
And I don’t mean popping for expensive sound panels. I’m a big fan of furniture moving quilts.
This is my design for a simple, one-person “kitchen table studio.”

I know you’re multiple people, but that’s just the idea.
I’ve been known to create a much larger “studio” with multiple pads. This is a movie animation sound shoot.
Note there’s one on the floor.
Being obsessive, I created a knock-down wooden frame to turn this…
Into this.
Also note in this broadcast shoot, there’s one folded up on the table. That can solve a number of reflection, comb and “slap” sound problems.
There’s a fuzzy rule about soundproofing opposing surfaces first. So if you can’t do anything about the ceiling, throw some quilts on the floor. Prop up some quilts on one of the two East-West walls and one of the two North-South walls. Best if you hang some quilts on all the walls.
And don’t poo-poo simple sound equipment. I turned in a voice clip that passes audiobook technical specifications with a tiny sound recorder (Zoom H1n) and roll of paper towels–in a super quiet room with no echoes.
