All good options, for the fully manual route I’d recommend a Cafelat Robot.
Definitely fits the bill: will last a lifetime, is small, simple, looks good (depending on your tastes of course) and leaves room for lots of experimentation. May be more expensive than the Pavoni pro depending on your region, but it does let you have more control given its manual design.
Downsides of manuals is temp management and no steaming (not a problem with a Bianca on the worktop too) but most users only really feel the need to preheat with lighter beans. The Flair 58 has electrical components and standard 58mm portafilters but I’m not quite as confident about their lifespan due to having more moving parts and electricals - but they are still solidly built machines for sure.
