The logic behind those suggestions is that a Moon druid is considered pretty ridiculous at low levels. Their wildshape ability to transform into a CR 1 creature at level 2 is amazing; it's like getting 30+ temp HP and some decent close-range attacks, all for a bonus action. (Check out the dire wolf, for example.) They're not quite so amazing late-game, just because there aren't a lot of good choices (yet?) and the utility of simply being a brute runs out quickly, but overall they are a strong choice.
Starting as a human and getting a free feat is also just generally strong. Druids tend to have lots of concentration spells, especially once you get to levels 5 and 7, so if you want to cast and then mix it up in melee as a wolf or something "war caster" is a good feat to have. The stat array given is also pretty strong, especially in conjunction with the "resilient" feat for Con, which is generally regarded as a strong feat because Con saves tend to be important, and you're already going to be good at Wisdom saves (the other most important one). You'll also want to take +2 Wisdom at some point, obviously.
With skills, it's really more like: Perception, Stealth, Survival, and then 2 more. Those two aren't bad ones, though; Animal Handling is especially thematic and Insight is just a darn useful skill you'll already be pretty good at.
I'll go further and say that Guidance and Shillelagh are great starting cantrips and Poison Spray is a good pickup later on. The rest of your spells will really depend on party composition and what you need for that day, but the nice thing is that druids always "know" all druid spells - it's just a matter of which ones you want to prepare. Healing Word, Thunderwave, and Faerie Fire are good ones to note.
There are other race combos that will work well, and if you want to be an amazing caster the Land druid is a great path too, but the above post is a very good answer to your question.
