Handling "blackjack etiquette rules" well means going past the printed rules. Blackjack rules fit on a card, but the game at a real table carries habits that the card leaves out. Players meet the dealer one hand at a time, cards are dealt face up or down by house rule, and every decision, from standing to doubling, has a best answer. Knowing the rules for beginners and the etiquette around them is most of what separates a calm session from a confusing one.
Whether blackjack is dealt face up depends on the house. Many shoe games deal the players' cards face up, while the dealer takes one card up and one down, or under British and European rules only one card until the players finish. Blackjack is never played with jokers; a standard deck or several decks shuffled together is used. Regional names such as Jamaican blackjack usually describe a set of house rules rather than a different game, so the rules printed at the table are what count.
Side bets sit beside the main wager and pay on things like a pair in the first two cards or a poker hand made with the dealer's card. They pay well and carry a far higher edge, so most strategy guides say players should skip them. Progressive jackpot rules on some tables add a side bet feeding a growing prize for rare hands. When the dealer and player both get blackjack, the hand is a push and the stake comes back.
Blackjack is partly strategy and partly luck. Luck decides the cards; strategy decides what happens with them, and basic strategy, a chart of the best play for every hand against every dealer card, cuts the house edge to around half a percent. That is the closest thing to a way to beat the dealer in blackjack: not winning more hands, but losing less on each. Players should double on eleven against most dealer cards, and on ten when the dealer shows less.
Asked about this

House rules decide: many shoe games show players' cards face up, while the dealer takes one card up and one down, or a single card until players finish.
Do regional blackjack names mean different games?
Names such as Jamaican blackjack usually describe a set of house rules rather than a separate game, so the rules printed at the table are what count.
