I just want to echo the recommendation for Alice in Borderland. If you liked Squid Game, this is just as good in its own way (I think I actually liked it better and find it a bit more rewatchable, even though I think Squid Game has a bit more visual style to it).
Season 2 just dropped as well so it's a good time to get into it. The full manga was told in those 2 seasons as well, apparently (haven't read it yet, just based on reading discussions on the show), so unlike a lot of Netflix shows, it tells a full story if it doesn't get renewed for another season.
I haven't seen any of the others you recommended yet, although Train to Busan was on my radar already.
Train to Busan should be available on Shudder. If you have space in the budget for trying out another streaming service, I'd recommend a few months of Shudder over a single rental, if the service seems to be up your alley.
