I've seen all those situations. The least common one seems to be two different dotted values: not because people use two noteheads in this situation (they usually don't), but simply because two dotted notes of different values on a unison doesn't happen as often as the other cases.
One dotted value and one undotted value is very common. It's specially useful for repeated patterns. In 6/8 time you often have broken chords in quavers with the first note of each group of three held down for the length of a dotted crotchet (Schumann, Abegg variations, finale, for instance). As a pianist I don't think twice about this: I read the figure with the shortest note values and see the notes that have to be held longer. Elaine Gould also gives an example where a minim (half-note) shares a notehead with a crotchet (quarter-note): the notehead stays white. She says this is acceptable in the context of repeated patterns and I agree with her. If you can get your hands on a copy of Debussy's "Etudes pour le Piano", have a look at N° XI, "pour les Arpèges composés": shared noteheads with no dots, single dots, double dots... not always self-consistent but I don't think any pianist has doubts about what Debussy wanted.
