Floats on small aircraft

I want to get a small float plane to fly from my lake to salmon streams
abt 20-40 miles away
in Ak. Land on the lakes or mouths and fish for Kings and then fly back
to my lake. Flight time prob abt 20 min one way.

wld i be better off:

1. just buying a supercub
2. buying a cessna
3. buy a fox built kit
4. Build a fox float kit

Hope someone can comment on this question -

5 Which kit wld be the best for that use? Short hops hauling several
hundred lbs + 1 or 2 passengers.

I have private liscense but not float rated yet but am retired and
ready for fun.

Are these questions too open ended?
