Alright, not much to go off of but I'll try based on my playtimes and exclude some very popular games.

Cook Serve Delicious (1, 2, or 3, my wife and I have probably 400h between the two of us). A fast moving cooking game that tests your dexterity. If you want to understand the flow of the game, I personally recommend trying CSD1 on an iPad if at all possible since the touch controls help you understand the flow of the game, then once you know the flow, you add in a keyboard or controller in CSD2 or 3. 3 is my personal favorite.
Cassette Beasts (51h). Pokemon always has a special place in my heart and I've bounced off other games that try to emulate it. Cassette Beasts hooked me with their creature designs and awesome soundtrack.
Zero Sievert (33h, Early Access). I haven't messed around with the big name extraction shooters like Tarkov or Hunt, but the appeal of a single player third person top down extraction shooter with a pretty cool style surprised me at how much I enjoyed it. The only reason I put it down was to save up for whenever it eventually releases.
Heat Signature (31h). Very run based, but the whole idea is you have to infiltrate ships all over the galaxy and accomplish your assigned objective on that ship. Maybe you need to hijack it, maybe you need to capture/kill someone, there's a lot of options. The fun really came with weird scenarios where you'd have to find unusual answers like breaking a window to launch yourself into space with your target and get scooped up by your ship, or hack the turrets and lure the enemies into a kill box.
Griftlands (18h). Card game similar to Slay The Spire where you build up your deck and get progressively more powerful against more dangerous enemies. The part I thought was cool is you can try to negotiate with your enemies just as easily as fighting them. Negotiation has it's own separate deck you can boost up over time.
Everhood (12h). A weird exploration and rhythm game with some good humor injected. I can't even really tell you what exactly happened since it's been a minute since I played it, but all I know is it got really philosophical and after it ended, I felt almost hollowed out at how beautiful/profound it was.
Antichamber (11h). A portal-like game that plays with spatial puzzles and navigating an ever shifting labrynth.

I could list out a ton more, I love these smaller and weirder types of games, but hopefully something sounds good!
