whole body workout routine, 3 times/ week for a 53 years male

Question

I am 53 years old, male, 82 kg and BMI of 26, with an abdominal girth of 100 cm. I am a very skinny person, and frankly, I am ashamed of my muscle size, especially the upper part of my body. I started regular exercise last April, and presently I train every other day by dividing upper and lower body exercise one after another. I got some confidence, built some muscles, lost some abdominal fat and feeling great. However, I think the routines are repetitive for most of the muscle groups, and I wish to have a whole body routine, preferably compound one for three times a week with 60 to 90 minutes per session. Please look for my current workout routine below. I prepared this list based on reading different books and online forums.

Could anyone recommend a simplified workout based on the attached list or any alternative ones?

If you can complete a workout then add 5lbs/1.25kg for that exercise next time. If you fail, try 3x again and if you stall then deload by 10%.
