I've been DM'ing for over 20 years from 2nd edition through to 5e and typically when working with new and old players alike, session zero is critical so that I can create the campaign around the character choices the players made.
Session zero is pre-play and typically involves character creation and conversations around what type of game the players may want, do they want a dungeon crawl, a murder mystery, an epic journey, etc.
The primary reason in a four-party game two melees, one healer and a spellcaster is the sweet spot is that with this make up the party has the greatest chance of success across a wide range of situations. Primary is the higher HP/AC and strength, dexterity, and constitution stats of melee-focused characters which can come in very handy in a variety of situations, not least of which is for the protection of the spellcaster who will likely be at mid to higher levels the deciding factor in winning a fight. The healer is also important to heal up the damage the melee characters typically receive along with other support spells such as Bless / Aid, etc.
It is possible to create a melee Cleric at higher levels if you put your bonus points to dexterity, strength, and constitution, though you are limited to bludgeoning weapons such as maces, etc.
