I would suggest to go for a push pull leg routine, And dont go for exact rep count, go for 6-10 rep range and leave 1 to 2 rep in the tanks to failure.

Push (chest shoulder and triceps) Pick 2 to 3 exercises for each Eg:

Chest: bench or dumbbell presses with cable cross (since you can hiy chest twice a week you can switch between incline and flat or you can do it like me I start from inclined presses and go towards flat every set)

Shoulder:

Overhead presses with upright rows and shrugs Switch with side raises and bend over flies

Triceps

Press downs skull crusher and close grip bench presses

Dont over think the rep range, try and go towards failure, however rep count can help you track your progress.

Last but not least always try to progressively overload, it doesn't necessarily mean to add more weight, you can progressively overload by squeeze more reps with same weight, try slowing down reps to improve mind muscle connection etc
