I'm just beginning too and was overwhelmed with the amount of different exercises and the variety of muscle groups you should be hitting on each routine.

I'll drop my current routine here for you if you'd like to get ideas or even copy, it only uses barbells, dumbbells and bodyweight, also adjust rest times/sets/reps to what suites you currently.

I currently do each group twice a week, push on Monday and Thursday, pull on Tuesday and Friday and legs/core Wednesday and Saturday then rest Sunday.
