Okay id suggests these games.
State Of Decay 2 and Sea of Thieves. Both games have just been recently patched, SOTs added content and SOD2 added lots of Bug fixes. Very enjoying games with friends. Obvious choice would be coop on both your gaming PCs.
I would also suggest Splatoon 2 and Mario Kart 8 on Switch but i dont know good they are playing in local mode. I have only ever played them online and solo.
We play Mario Kart 8 on Switch already. Should have mentioned that as well. Splatoon 2 is something I intend to get later for us
