i understand your frustration. you're about to "milk" those beginner gains to their full extent, and you're wondering what's next.
first, ask yourself what your goal is (probably to get even stronger, and get even more muscle size, right?).
secondly, how many days per week do you want to train? (3 is enough, 4 is ideal for an intermediate lifter, imho)
finally, think about your weaknesses. are your shoulders lagging? does your back need more work? etc.
when you've answered these questions, think of exercises that will bring your lagging parts up.
in my honest opinion, upper/lower or push/pull is what you're gonna want to do. look into 5/3/1 BBB, PHAT or PHUL if you want cookie cutter premade programs. but if you know anything about programming (and even if you don't, now is the time to learn), you should program your own workouts, based on the weaknesses/lagging bodyparts.
generally, these are the movements you'll want to choose from (and advance in):
vertical push: overhead press, push press, landmine press, dumbbell press
vertical pull: pullups, chinups, there are a million variations
horizontal push: bench press, incline press, dumbbell press
horizontal pull: rows (barbell, dumbbell, bodyweight, machine, chinese style, cable)
hinge: deadlift (conventional, sumo, squat stance, romanian, trap bar), kb swing
squat: back squat, front squat, bulgarian split squat, box squat, etc.
and finally, accessory movements, to add to your main lifts:
lateral raises, band pullaparts, facepulls, biceps curls (straight bar, ez bar, preacher, cable, etc.), triceps (cable ext., skullcrushers), dips, pushups, more pullups, abs, calves, forearms, etc.
1. choose a template (as in fullbody, upper/lower, push/pull, etc) and periodization scheme
2. choose main lifts
3. choose accessories
4. done
hope i helped at least a bit user
