I qualify as an older guy and when I came to GT over a decade ago I had been 'off' guitar for better than 30 years.  So, what I write is based on personal experience and old fart wisdom... and a history similar to yours.  And is my opinion based on all of that.

Start/stay with the Fundamentals courses (see guitartricks.com/beginner).  If the Fundamentals seem too basic or too easy... good on you!  You'll be able to go through the courses faster than a newbie.  But there is no doubt you'll find something that teaches and challenges and makes you a better player.  

Then pick the set of courses of the genre you're most interested in.  If you have the time and will, you can do more than one course at a time... skills overlap and reinforce.  In other words, follow that Core Learning System chart shown at guitartricks.com/beginner.

Once your basic skills are more or less solid you can search GT for specific 'things' you're interested in, e.g., theory or specific techniques.  GT is loaded with such lessons.

I always recommend two additional approaches; one, keep your practice sessions varied, i.e., not just a lesson, but a little here, a little there; technique, exercises and drills, course lessons.  Mix it up in practice sessions.  Two, songs... unless you want to be 'just' an instrumentalist, bring songs into your practice as soon as you can.  GT's catalog is full of easy to advanced songs... start checking it out early.

Most important, IMO, is have fun.

Welcome to GT.  Good luck,
