Wanting to start DnD with Family

As the title suggest. Ive played dnd like 10 or so years ago, in a big rpg fan, and recently been on a huge bg3 kick thats lead me to dnd youtubers and i want to try it out.

The wife has been on a big fantasy kick as well with books like fourth wing and acotar.

My oldest(12) is a big art nerd.

Also would like to see if my 8yo would be interested.

I dont have any books or anything. Where would be the best place to start?
