1st time builder

Hello,

This is my first entry and it's a loaded question...
My husband & I are building our 1st home and although we've found a great builder, I'm still very overwhelmed by all the details involved. I've done a lot of reading and research & our builder has different vendors for us to check out to make the final decision of who to go with. Carpentry & cabinets, flooring & counters are on the top of my list. Any suggestions on the best wood and stone to use? 

I'm also hoping someone can give me feedback on building a high quality home & the areas to focus in on spending the most and the least on.

Thanks for any feedback you can provide!

Have a great week!
