Great video and I really love how open you about considering other types.

I'm not sure what you are but you are more expressive than I thought you'd be based on your picture. That said, I don't think being expressive especially on cam proves whether or not someone is an Fe valuer though. Ethical types, in general, have good or great Fe usage. IEEs actually have stronger Fe than IEIs (theirs is 4 dimensional while ours is 3 dimensional) and their Fe is demonstrative. EIIs have 3 dimensional Fe too but it's their ignoring function so the proverb "still waters run deep" often fits them, in the sense that they don't show their passionate nature as much but I'm sure that they can be expressive too when they want. So yeah, while you could be IEI, Fi valuers can be expressive, too.

Here's a link that talks about VI and its manifestation through the demonstrative function. Maybe that'll help a bit. Demonstrative ethics fits me well and I also get a lot of the remarks in the descriptions about my smiling from others like my mom.

I personally think it's better if you just learn more about the theory and type yourself instead of relying on people's impression on you based on picture and a 2 minute video. It can be helpful but it's more satisfying knowing how the system works so you are more confident in your typing. There are many ways to type yourself (Reinin, temperaments, model A, intertype relations, romance style, erotic attitudes, descriptions, subtype theories, DarkAngelFireWolf69 communication styles, dimensionality of functions, quadras, tests, etc). If you find that you fit the criteria for IEI or whatever in many of these, you'll be more confident in your own type. Good luck!
