Split to Kotor travel by bus or ferry, boat?

I am flying to Split airport in July and considering to take bus from Split to Kotor so I can slowly travel further from there to Albania and Greece.

I can see there are buses from Split to Kotor but Im not sure can I also use some ferries or something similar like boat day trip from somewhere to Kotor or any other place in Montenegro?

And also what is the best way to reach Montenegro, Albania and Greece from Split?

Thank you for your time to answer this
