I've used WoW-Pro for years and in WoD, Legion and now BfA it's been awesome for just going on auto-pilot and working your way through a zone. It has 3 levels of depth you can set, so you can set it to just do 1) the main story, main points of interest and rare mobs and treasure that aren't far off the beaten path; 2) every quest with a more thorough dive into the side stuff; 3) absolutely everything.
Never ever pay for leveling guides. Want/need to learn about and use. Dugi is hosting a contest where you can get. Saharun is one of croatia's loveliest but least known spots (picture: alamy). Open my map to see where the nearest quest takes place and go there, through the questtracking you can quickly see what is to be expected of you or even when you look at your tooltip while hovering over mobs. It sounds unrealistic but the video promotion of the guide clearly shows how you can do it. Unfortunately it is a website and you may have to tab out if you aren't sporting a multi-monitor set up.
