You should be fine with a new build. Building your house will be rewarding. Old house’s look cool but I’ve learned from experience it’s not worth it dealing with mice, things constantly need repair, etc. At least that’s how we feel because we have always done everything ourselves. My house was built in 1946, its cinder block. After we did the foam under cabinets we are good. My great grandfather built it, nothing is square but it’s solid. We’ve remodeled entire house. We have had a minor problem during remodel but we kept the spray foam handy. Nothing will mess with your head more than being sleepy getting up at night seeing one run by. A couple years ago he drilled hole in floor for his cb antenna wire. We had lots running around in the pantry. Didn’t know they would eat flour. We finally caught them all.
Did you incorporate stainless steel or brass wool when you caulked cracks? Mice will eat through caulk or spray foam, but the metal wool stops them (they don't like chewing on metal :) )

No just used spray foam & it was over twenty years ago. Knock on wood, no problems as of today.
You can put some peanut butter out on a plate to test it :)
