Welcome!
Only you can decide ultimately, however you're looking for opinions so this is my take. You haven't ridden in a while and seem a little tentative about the road bike from your test ride. Yes, you just might get real relaxed soon on one or you may be afraid of it and end up not riding because of that. You have a daughter who you said will need a bike. Depending on your pocketbook, you could get a new bike that she can end up using if you need to move up, or you can get a craigslist bike and if you want to upgrade in a couple of months you can post it back on craigslist and probably won't lose a dime on the deal if you shop smart. If you end up really getting into cycling you'll want a better bike at some point and at that time deal with a local bike shop and invest in a good quality bike. Until you know if you're going to like it it's kind of a crap shoot and it could get expensive. Money's no object? Go for the moon out of the chute.
Beware, this is an addictive sport!
