You're definitely not an LII. Valuing

is not the same as preferring it. Remember, we value what we lack (which is part of the basis for dualization). If you were LII,

would be something that permeated every aspect of your life. I believe you're an SEI... and I'll explain why.
First of all, your descriptions of your past are full of sensory information, and in your video, you "talk with your hands" in a way that suggests to me that the concepts at hand are fundamentally connected to sensory information for you. This is consistent with a dominant

function because the dominant function is generally how we store most of our information. (as a dominant

, I generally remember things as logical patterns and structures.) Also, your fascination with perception itself fits with this. Many of the interests you list are interesting for

reasons.
Second of all, your tendency to take responsibility for the state of the social interactions around you (making sure people aren't left out, setting up events, etc) is fitting with a strong conscious

. The way you like to challenge social norms fits with

being your creative function rather than your dominant function as well, always providing new material for your dominant function to sort, filter, and incorporate.
The way in which you value

fits with it being your mobilizing function, and your sarcastic humor fits with

in a demonstrative position.
What you said about "thinking outside the box" fits with

as your suggestive, or dual-seeking, function. You like being presented with novel perspectives and ideas, but have difficulty providing that for yourself.
