For ease of care I would probably start with coral that primarily use light to grow they are also the easiest to care for

Anthelia and Xenia are very easy to look after but both tend to grow like weeds

Hammer and Frogspawn are also easy to care for

Zoa's another easy to care for

Some types of brain corals are also easy to look after

I have all the above never had to supplement feed them just did weekly water changes and gave them good light but some swear by supplement feeding the choice is yours

Most soft coral is easier to care for but most branching coral tends to be a bit more difficult to look after and require some extra attention and supplemental feeding

Again it's up to you
