Less is more, imo, but you could probably take a few out for better airflow. be systematic and stagger the leaf loss among colas evenly. maybe, work across left to right and only take off the left leaf in areas that needs it. or inward facing leaves on centrally located colas ... it just helps even it out if you create 2-3 simple rules to follow. 2nd vid doesn't look like it would need much... the plant is noticably praying more in 2nd vid too. looks pretty happy all over.
The plant will shed excess leaves. it'll suck them down of resources first, then they can be lightly plucked off or they just fall off.
i don't think removing foliage helps yield. in fact i expect it to have the opposite overall effect. It doesn't make it a bad idea on its own. you may be able to get a higher proportion of A nd B quality nugs, for example, and vast majority of the loss would be larfy trash anyway. leaves removed from top will impact local buds more than the gain below (primarily due to inverse square law). The added weight to the better nugs probably won't outweigh the lost larf + any off top. if you cook edibles or make hash, this may not be the best for you. Good larf makes some of the best hash and just as easily used for extractions. So, context matters.
Avoiding microbial growth is another excellent reason for some minimal defoliation. leaves resting on other leaves creates resting water which is a foothold for microbes. Low air flow and higher RH% around leaves is an opportunity for microbial growth. This stuff is ever-present in the air unless you got a lot of hepa air filters running and replace them often. uvc would help too. Good circulation obviously helps too.
i'm so scared shitless of microbial growth i usually overdo it slightly. 2 years no problems like that but last few grows.. big problem.. lol, it's always there in the air.. waiting. i'm still working back toward being reasonable about defoliation, lol.
