Lame answer but YouTube. Channels in the vein of freecodecamp.org and Stanford Online are incredible. Any skill, hobby, repair, or question I can think of probably has videos there.

I use youtube because most educational content is available en masse there for free.
It would be great to see more on Odysee.
