Good on you for trying to do some research. As others have indicated, you have a long time before you need to choose a community. Task 1 is getting your grades up so you can get in to a commissioning program. Until that happens everything else is just trivia and nice to know.
That said, USN H-53s do not routinely deploy to carriers. However, they do sometimes deploy to LHD/LPDs if there anti-mine mission is needed and there is no accessible land base nearby. The h-53 squadrons will deploy overseas areas to maintain an anti-mine presence.
USN H-60s go everywhere that has a hangar and a landing pad. 60Rs (HSM) deploy to small boys and to CVs. 60Ss deploy to USNS ships, LHDs, CVs, and some land based sites.
The life of a nugget in any type of USN Squadron is largely the same. In rough terms JOs spend three years in their first Squadron and deploy twice. In that time they train in the aircraft to go from becoming an useless sponge to a fully qualified member of society. In addition, JOs will have ground jobs of increasing responsibility starting with something along the lines of licking envelopes and finishing up running major Squadron programs.
