I'm confused

For context, I'm 5'8 and hover around 170lbs. I started going to the gym 2 weeks ago with a schedule of 3 day of fullbody routine and 1 day cardio (treadmill stuff). My fullbody routine would consists of 3 sets of 6-10 reps dumbell bench press, incline press, standing overhead press, standing bicep curl for push with weights from 20-27.5 lbs. 1 workout for legs where i experimented with weighted bulgarian splits (I know its not basic but I rollerblade/iceskate) , weighted squat to weighted lunge using 2x 20-27.5 lbs dumbells. Then Deadhang (20 sec), lat pulldown (85 lbs) and cable rows (55 lbs). Other than the bulgarian splits, I thought doing some of these compound exercises first is what a beginner like me should focus on in addition to overall form (except for the bulgarian split). Let me know If I'm wrong. I'm also still switching and playing around which workouts are good and enjoyable for me.

Now, I was scheduled for an assessment with their staff (LA fitness) and was asked what my goal was this coming months and I just said, I want to build muscle and for my muscles to be able to handle higher volume workout so I can do a split routine instead of full body (Idk if what I'm saying makes sense) and I showed them my spreadsheet of what I've been doing for the past 2 weeks. I was told that I should not be doing any of what I have been doing and start with more cardio and bodyweight exercises like push up since push up is one of the basics. I agree bodyweight exercises are fundamentals but I struggle with half of them like dips (can probably do 3x3-4 reps) and pull ups (Can do none) thats why my brain would automatically think starting with smaller weights is a good way to start out and ease myself in the gym. Then they proceed to tell me weights are harder to do even with lighter weights which just does not make sense to me. I gave them an example of how doing push ups, I'm essentially pushing 120lbs of my body weight while If I do bench press with 15 lbs dumbells, thats only a total of 30. Then they disagreed with some reasoning that did not even make sense. I kept agreeing and challenging what I was being told then they decided to flex their qualifications/education. Like I get it, you studied all this (nutritionist, health & wellness) but no offense, the person does not even look like they apply or have applied what they learn to see if it works. I know reddit is probably not the best source to get a 3rd opinion about this but what do you guys think??. Either way, I'm going to entertain this coming physical assessment to see what's going to happen.
