I wouldn't listen to anybody, if you like cardio and it makes you feel good then keep doing what you're doing. I know some people who get euphoric from running it's a release for them, that was sure as heck never me I joke that cardio is how God punishes me for my sins. The only thing I will say is that in this world the way things are now it's good to have some size, it's good to make people think twice before they decide to challenge you or decide if you're a target. I don't expect everyone to subscribe to that mentality but the world has become a less hospitable place lately and everyone is trying to get a piece of someone else it seems. I remember on the old forum so many guys would say "I want to look like brad pitt in fight club".....brad pitt in fight club would get his ass handed to him by high school kids and girls would see him as a novelty toy, always laughed at that.
For power lifts (shoulder presses, chest presses, dead lifts, squats, lunges, maybe even rows) I would add a little more weight and do less reps, save the ten reps for the accessory lifts. Also not sure why you're specifically concentrating on those 3 exercises and also 3 days apart as a rule is probably overkill. Honestly you're overthinking it a bit, I don't mean in this in a negative way at all but you seem like an extreme beginner from some of these things you're saying, it would benefit you to just keep things simple. Have you ever had any kind of athletic training where strength was prioritized? Being able to do 10 pull ups and 20 dips is not necessarily a lofty thing whatsoever, especially being in shape and lean. I don't say that to put you down I say that to illustrate your inexperience and to compel you to keep things simple for now.
Here is a beginner sample workout with generalizations instead of specific exercises, you can fill them in as you prefer:
Stretch/Pull ups/Dips/Push ups to warm up before each workout and again after workout
Monday Chest/Tris
Some type of chest press
Cable fly's or pec deck
Second type of chest press variation
Pull down tricep exercise
Underhand or single handed tricep exercise
Tuesday Back/Bi's
Deadlifts (skip if you have back issues)
Some type of row, I prefer seated
Shrugs
Second row variation or stiff arm pull downs if you skipped deadlifts
Machine or bar bicep exercise
Dumbell bicep exercise
(for biceps try to get straight, hammer and rotating grips all in there)
Wednesday off or cardio
Thursday Legs/Shoulders
Squats or Lunges
Calves
Another leg exercise
Some type of shoulder press variation
Lateral, upright or front rows
Rear delt exercise
(shoulders are really important for size and physique, they are often overlooked don't be afraid to work them hard there are many shoulder exercise variations)
Friday off or cardio
Saturday light full body
Pick two exercises for each body part, arms maybe just one. You don't have to go all out here you can do less sets, you've already hit every body part this weekend this is kinda just like finishing them off
Sunday off
You can skip the full body day if you're only lifting 3 days a week and just space out the others, mind you if you're exercising doing your cardio on other days you're still working your muscles.
Lots of ways to skin this cat, this is just an example. Don't fixate on rules and specifics there is no need for that yet, maybe in the future when you learn what your body responds to and what needs more work things of that nature.
One thing too late to edit, that shoulder exercises should be raises not rows and for back your main exercise besides deadlifts should be pull downs.
Also I'll emphasize this again, you're there to push yourself. Not destroy your body but absolutely push yourself, don't just go through the motions on anything. I always tell people "be an athlete", come at your workouts strong and push through them.
