Aww Gems, I'll be sorry to see you go. Have a safe trip!
To answer your question about Mank, I haven't seen it and it really wasn't on my radar. I've never seen Citizen Kane and I don't have any real affinity with that era of cinema - I've seen very little films from before the mid-sixties, and most of what I've watched from that period has been either Japanese or spaghetti westerns. (As a sidenote, anyone who loves spaghetti westerns should hunt down the recent Indonesian film Marlina the Murderer in Four Acts).
The film on your latest list that's of most interest to me is The Eagle has Landed. I remember seeing the trailer at the cinema as a kid and it looked soooooo cool, but I've never managed to watch it in the 43 years that followed!
Of the films I've seen over the last few months, the absolute stand-out has been a Taiwanese film A Sun - it should be available through Netflix, and I think it would automatically be in my top-10-of-the-decade list. A word of warning though: describing it as a tearjerker is probably an understatement - it was more like a hardcore sobfest.
Other films I've seen that should be recommended:
Network (1976) - it felt scarily contemporary
Mr Donkey (2016) - a (very) black comedy from mainland China … I think Ren Suxi (who was also in A Cool Fish, which is still showing on SBS OnDemand) is fast becoming my favourite comic actress
My Prince Edward (2019) - a clever and very honest sort-of romantic comedy from Hong Kong. While it follows a very well-worn romcom template, there's a twist … it isn't funny. Or romantic.
I also revisited Storm Boy (1976) for some warm nostalgia … I would have loved to have a pet pelican when I was a kid.
