I’m very amused by how your low end PC is still better than mine (I have a GTX 750)

I went through some of what I’ve played and might interest you, as well as some classics.

Counter Strike and its younger, more anime cousin Valorant - They’re both 5v5 FPS games, although Valorant has named characters its not quite like Overwatch where they act like classes, everyone is expected to be shooting and most abilities are different ways of using flashbangs or smoke grenades.

Warframe - Ninjas play for free, but they wait 72h for a new frame to be built. This is probably the non-idle game that I’ve played the most, and I don’t regret most of it. The biggest downside is that you’ll want to find a good community as the game relies heavily on trading and teaming up for specific grinds after you’re done with the basic missions. Still a shitload of fun.

Paladins - A hero shooter with a bit of a moba-ish stink. Aside from having different characters, you also build modifiers for their abilities plus buy items during combat, which makes for a very hectic and somewhat hard to pick up gameplay style.

Goose Goose Duck - A social deduction game with classes. While Among Us made the genre fairly popular, the ‘classic’ ones like Werewolf or Blood on the Clocktower relied on having special characters with different abilities, and this game leans more towards that style instead of just having ‘plain’ characters.

Guild Wars 2 - A classic MMO, to the point where its even difficult to describe. I have not played it since it went F2P but it is a very standard fare of the genre. Pick a class, have a little personal story, do quests and jobs for everyone with an exclamation point over their head until you’re dead.

PlanetSide 2 - A massive cooperative shooter. Take part in large scale battles against other highly uncoordinated teams, fail to pilot every vehicle you find, blow up your teammates, somehow take over a territory successfuly.

We Were Here - A coop puzzle game that relies heavily on voice communication. Help your partner solve puzzles and survive a deadly environment by exchanging clues that only each of you can see, or die trying.

Helltaker - Brutal puzzle game. Go to hell to find your waifu.

Crusader Kings 2 - The eponymous grand strategy game. Read a dozen walkthroughs on medieval eras and its regions, attempt to take over Europe, father a dozen bastard children and have half of them sent to the oubliette.

Path of Exile - The ur loot game. Behold the most extensive skill tree man has ever created and weep, then kill a million different monsters while building up your perfect murder machine.

Marvel Snap - My current addiction. Have been playing it since october and it might be time to think of what I’m doing with my life. Duel over 3 locations with another opponent, attempt to score the highest amount of points in two of them to win. Learn why Galactus is an asshole or join him.

like most classic F2P games, a lot of these have paid options that ‘speed up’ your content, be it selling new cards or characters, or having QOL upgrades. Aside from Warframe, I’ve never paid for any of them and still had enough fun.
