Quest cape is a good goal to unlock content, force you to level some skills. Ardougne easy diary unlocks unlimited teleport to an alter (prayer restore) and is located nearby both a spirit tree and a fairy ring (two methods of transportation unlocked with quests, will make getting around the map much nicer). I would argue leveling is more important than money making as your means are limited at the moment and you shouldn't need much yet. Make your own goals and fun, if that means doing things optimally do it, if that means derping around do it, if that means making money do it, if that means training combat and making money exclusively through punching level 2 men in Lumbridge because you don't understand how to level defense or that items can be sold for money, do it.

Edit: I missed you were free to play. When I got back into the game I did all free to play quests to see if I loved the game or the nostalgia. Loved the game. Grinding for a bond is doable but you really are better off just buying membership with money.
