Beautiful new place! congrats, my wife and I also had to deal with the CovidWedding stuff... NO FUN! But congrat's I'll be following along from Oklahoma.
It would definitely be worth it to just build a new one on-site. one thing you can do with the old one to help offset the cost is to post the old one online and let other people that want the metal and lumber pay you for it and make them take it down.
I am in the Post Frame industry, the question comes up all the time I typically tell them 24x24 is the smallest I would recommend a garage to be. It's tight but doable. I usually say go with a 30x30 if you have the room but need a smaller structure.
