The canoe man knot is a simple bowline and a lot of these other loop knots are bowline with a bight or 2 or 3 bights.
In fine mono a bowline or improved clinch is sometimes hard to tie but a bowline will hold.
I use a Uni knot for attaching lines together or for a loop knot —I use it lots.
Attatching a hook I sometimes use a Paloma’s but mostly a trilene knot
