First off, good going on getting 2 job offers! You did really well in the interviews.
Second, congratulations on the new job!!!

You won't know until you getting going in it if it is the right position for you. Don't make any assumptions until you try it. The good news is if the second position was interested, they may very well be interested in the future if this first one does not work out. You can always talk to them again in the future. Give the first one a wholehearted try and go from there. It might surprise you.

Good luck in your new position! (((((((justmom)))))))
