- stuff I play myself
- something I can explain to the 70yo parents in a few minutes before the game
- easily available (either recent, or a classic)
Here's five recommendations:
- Cacao (https://boardgamegeek.com/boardgame/171499/cacao)
- Carcassone (https://boardgamegeek.com/boardgame/822/carcassonne)
- Alhambra (https://boardgamegeek.com/boardgame/6249/alhambra)
- Ticket to Ride (https://boardgamegeek.com/boardgame/9209/ticket-ride)
- Samurai (https://boardgamegeek.com/boardgame/3/samurai)
Enjoy playing it against my 8yo but have also had a few nights playing with friends who've enjoyed it also.

Cooperative: Pandemic
Language Based: Codenames, Taboo
Competitive: Ticket to Ride, Splendor, Munchkin
Card: Monopoly Deal, Exploding Kittens
Notably absent is Catan, which has a steep gap between those who have played before and novices, with an especially punishing snowball effect.
It's not that hard and it's beautiful.
Lastly, the "new player" card pack that comes with the game works well to get someone up to speed and competitive quickly (and is an idea other games could afford to learn from).

However, some of my recommendations include Parks, Wingspan, Splendor, Azul, Castles of Mad King Ludwig, Potion Explosion, Kingdomino, Lanterns, Ticket to Ride, Pandemic: Iberia, Carcassonne, Concordia or Concordia Venus, Quacks of Quedlinburg, Treasure Island, etc. There are literally thousands of games that could meet the criteria of 3-5, simple rule set, 60 minute play time, and fun game play.

Pretty much every game on the first page of that list would meet your criteria.

From the top options presented I can recommend
Kingdom Builder - incredibly easy to learn strategy game with just enough depth to keep it interesting over multiple plays
Love Letter - one of ourmyregular games to kick off a game night. Quick to pick up, quick to play, and fun.
Coup - similar in many ways to Love Letter, but with bluffing, which makes it much more cut throat, but it plays quickly enough that no one gets angry, they just get back at you the next game.
Colt Express - exciting game with a unique "programming" like mechanic that's very simple to pickup, and allows for some playfully grievous player interactions.
Gaia - underrated game that shares a lot of mechanics with the more popular Carcassone. Very strategic, and the advanced version amps up the competitiveness.
Carcassone - one of the most popular games around. Can also recommend Hunters & Gatherers.
Stone Age & Puerto Rico - great entry level worker placement games.
Granted, it doesn't have every game imaginable (Catan, Munchkin, Risk) but its selection is large enough to find good games for just about any group.
If you want something more advanced, this doesn't exactly fit your criteria, but I highly recommend Terra Mystica. One of my favorite games of all time.
I think with five players an hour is pushing it for Kingdom Builder, but of course this will vary if you've got players who are just generally faster at playing board games.
Note that the boxed Kingdom Builder game is actually four player, BGA is providing a five player expansion (because it's a web site, so the extra little wooden pieces don't cost anything) but if you are in the real world that's an issue for five.
I feel like Stone Age is a better introduction to worker placement than Puerto Rico but I wonder how often you'd really get a five player game in an hour. We generally take 90+ minutes for four players.

You play three rounds, if you're fast you can even squeeze it into the lunch break.
This game manages to be fun and also teach you a lot about human greed.
You can explain it to a person who's two-three beers in and they'll get the rules well enough to start playing. Rounds last 5-10 minutes depending on how much people start analyzing the cards on the board. You can play as many rounds as you want.

I've got to try the Batman variant!
