I agree with @ernohannink statements. A business name is something you should consider. I considered it, but still went with my own name.
“But, I’m wondering if I should have my name be the main domain and the other be a subdomain because what if I change to focus on something else in a couple of years?”
Not sure why you would use the 2nd domain as a subdomain. I don’t see any benefit in that. Technically a subdomain is subdomain.mydomainname.com
If you do chose to use your own name for your business I vote for deairby.com
