How big is your house/living space - particularly if you have no kids living with you?

I have worked from home 10+ years. I live in the south and the two houses I have owned down here have been large -- 2600 +/- 50 sqft and in the far suburbs of a major metro area.

I have always had either kids or an elderly parent living with my wife and I - plus at least one dog. There was a lot going on, but I always siloed a bedroom with a door to myself and I was content with that. I don't need more than that 130 sqft to put a desk, a chair, some monitors and a white board.

Life has since moved on a bit. The kids are gone. Elderly parents and dogs passed. We're looking to move to a new part of the country and I'll continue to work from home. It's now myself, my wife - who is trying to bootstrap a passion project that involves recording videos into a home-based business - and 2 cats.

The area we want is established and most houses are built 1995-2005 and smaller - 2000 sqft. Most are 3 bed/2 bath or 3 bed/3 bath. But there is significantly more to do - restaurants, bars, nature, are all very close by if we can get by with a smaller home.

As I'm looking at houses, I am feeling internal pressure to keep square footage. Really for no other reasons than to not be on top of my wife doing her work (controlling the soundscape is important to both of us) and to have a bedroom that's away from the rest of the household so that I can have some space and "a commute" that's longer than 3 steps from my primary bedroom to my office bedroom.

I imagine soundscape can be solved with some anechoic panels in both of our offices. I feel like I'd be fine with the short commute given that I will have so much more to do (and a night-and-day difference in my desire to be outside) in this new city.

So my question is - am I being too sensitive to this size thing?
