Some great solves in the video, congratulations!
As a side note (as with many of these 'sub x with x methods'), I would call it sub-10 with 20 variants. I see only two methods, layer by layer (of which CFOP, LBL, ZZ, etc. are all variants), and Roux (of which there are variants). A true sub-x with x methods video would be some combination of LBL, Roux, Corners first, Columns first, belt method, and/or other unique methods.
