Definitely advocating for this as well - this is something Freeform does really well.
For example, here is how Freeform handles a video URL (i.e. YouTube), and a regular URL.
And here is how the exact same context is displayed in Obsidian Canvas:
Freeform’s display and user experience is much nicer and with much less friction. 99% of the time I would prefer accessing a link or video URL saved in Canvas in an external web-browser instead of attempting to wrangle with it within Canvas, which causes friction and turns me away to other tools.
