Without a doubt the best resource I found was Kirk Byers Ansible course. Info below. I troll for good sensible courses and they are either very server/sys admin focused or very simple.
You are 100% correct that there is quite a lot out there using the deprecated models. I tried to go over that in a presentation I did at Interop last year and the companion repo is the first link below, in case its of any use.
I have a series of Ansible repositories that I use to do demos. The Cisco ACI one may also have some examples you can use.

In case its more of a set up issue, this may be of interest.

Kirk's course which started Sept. 10. Reach out to him if its of interest to you. He is very accommodating and if there is any way to get you in, I'm suspect he will. I know he's been working on updating it so it may be just what you need and trust me..it is worth the money.

I'm working on getting all of those updated but as you know...time is always in short supply!
