At 8:29 and early in the video, those are sedum. At 20:09 looks like coreopsis. We have that plant and it blooms from about March until December some years. I love your "inspection tour." We do the same thing, almost daily, and call it a garden tour. Looking forward to more future videos. Sorry to bombard you with comments on a lot of them. I just discovered your channel and am binging on a lot of your videos, lol.
