How busy is your life?!
A cafetiere is probably only beaten by an aeropress in term of least faff coffee solution due to the minimal washing up. Biggest downside of a cafetiere is the left over sloppy ground situation - so i prefer any filter method for ease of disposal - but the aeropress is also just bung coffee + water in, add tiny filter paper to screen, screw together, wait 2 mins, plunge into cup, unscrew, pop coffee and filter into bin, run everything under tap - enjoy.
Failing that posh instant.
For less faff than a cafetière you’re probably looking at Nespresso. Honestly don’t go near home espresso, it’s for people who love faff!
