Ok, if you are against hard feelings, cross off anything that is directly competitive, that would be any game where players directly and willfully interact with each other in a way where one gains while another loses as part of the core gameplay. To varying degrees things like blood rage, root, monopoly/solarquest, everdell, 7 wonders, clank, carcassonne, ticket to ride, dominion, etc.

If your group must have competition, you’ll need to stick to independent competitive games, this is anything where players are primarily taking actions in their own space and are progressing largely independent from each other. Example recommendations include things like Quacks of Quedlinburg, Shifting Stones, most roll and writes (welcome to series, cartographer with a minor exception), cascadia, verdant, etc

If you can do without competing with each other, cooperative games are definitely the way to go to minimize hard feelings (it’d only come up then if someone thought another player did something suboptimal causing a loss). The variety here is actually pretty large: simple trick taking games like The Crew series Information sharing games, like Mysterium “Combat” games of all complexities (generally ascending: Lord of the rings storybook, marvel united, D&D board games, Heroquest, Stuffed fables, Atlantis Rising, legends of andor, horrified, Arkham horror, marvel champions, mansions of madness 2nd edition, spirit island, Gloomhaven) Mystery/puzzle games (Adventure Games series, Exit The Game series, Animals of Baker Street)

I’d also like to call out 2 other games specifically: Stella, while it is a 1 winner competitive game where your score depends largely on other players, the push your luck and prisoner’s dilemma aspect of how you earn points I think largely removes the feel bad aspect of competition. Kitchen Rush: pure cooperative, but it’s also a real-time game where everyone is taking simultaneous actions to run a restaurant in 4 real time minutes stretches.
