Most of Android phones (Kompakt should be in nutshell) allow all asked questions, minus e-ink related.
E-ink question is slow screen refresh for transitions, picture viewing, web browsing, its less visible on viewing text
Beside enhanced privacy and easy offline, I like grayscale e-ink as Retro nostalgia factor and enough for workload
and some fun. Quality sound can compensate and I hope speakers, audio jack and good mp3 player will complement it - I imagine some srylish wired and BT headphones by Mudita too.
Good software whatever is chosen to be and APK Sideloading freedom.
Maintaned optimized OS for specified hardware, even its lower specced then average Android can turn too good experience. Updated and growing by user demand / request is true FLOSS OS.
