I think you got the noise problems licked, and you have vocal presentation down, but it sounds exactly like you’re recording in a bathroom.
There is no reliable “DeVerb” or echo reducer, so I’d be throwing towels or blankets around. There is a video from someone who performed a test in a bathroom and then ducked under a heavy towel and magically turned into a studio production. I know you can’t breathe under there, but that’s the concept. I’ll see if I can find it.
I like furniture moving blankets and I designed a “Kitchen Table Sound Studio” using them.

The fuzzy rule is to deaden opposing walls. Throw one on the floor, one on the East wall and one on the North wall, for example. That should help a lot. Let’s see, in my house, that’s throw one on the floor, one over the shower curtain rod (north side of the room) and duct tape one over the windows (west side). That’s minimum. That might be enough. If it’s still not perfect, do the two missing walls.
You don’t have to use moving blankets. You can do it with regular blankets or heavy towels. The magic word is “Heavy.” If your blankets look great but don’t weigh anything, you can leave them in the credenza.
Same thing with acoustic foam or panels. If you can blow one of them off the table with your breath, send them back.
