Hello! Sorry to hear of your woes but very much welcome back!
Out of the three lappies (yes a laptop can work fine) you've linked, I reckon the third will be the most capable. Yes, the others will run the game, but at various degrees of reduced performance. I certainly wouldn't recommend gaming on 8GB of physical RAM despite whichever GPU you choose. And the RTX2050 model will struggle somewhat. *
I've never used Box - all my PC's have been built by Scan. I highly recommend them and their system building site lets you really customise a build to your needs. Not the cheapest folks, sure, but you do get some really great after sales.
Anyway, again, welcome back!
* As a reference point, I have an AMD Ryzen 7 5800x, 32GB RAM, and an RTX3080 (on a desktop PC with some other bits and bobs) and this lets me play in 4K without too much trouble. It does stutter every now and again though. Another point is Wi-Fi 6 (802.11ax). This is a great to have if your router supports it. I'm using this to play - I really want to get an ethernet connection though - although my router only support the earlier WiFi 5 protocols; which is slower.
