What about snails or the catfish that are sold as algae eaters ?

As far as I know, there are no species of temperate catfish that would do
the job of cleaning the bottom of a pond.

However, if you live in the tropics, you
can always add a plecostomas or two. :-)

No. afaik, there is simply no such thing as an "algae eater". Most of the
fish that will do this job, do it _only_ when small. Most of them become
completely omnivorous when they reach adult size. Even plecos have been
known to damage koi.
