miniDisc is a good sweet spot i think. its something physical but not as bulky as a cassette player
if you get one that has netMD support then you can transfer new music onto it just like it was a usb drive. there are even chrome websites that will let you do this so you dont have to install any software
theres also the compression modes where you can fit either 3 or 5 hours worth of music on one disc so you could easily make do with just 1 or 2 disks if you were going out somewhere for the day
one of my favourite things when i switched to linux first was using the meta+Q hotkey to shutdown a program (this was with PopOS i think). with windows there is alt+F4 but some programs only use shift+alt+F4 which makes it a lot more confusing. on top of all that if youre using a laptop then its another keypress for the Fn key in some cases
